SPOILER ALERT!!!
Last Stand? Based on the end of the movie, I highly doubt it. Also based on what happened in the comic books, I highly doubt it. Watching this movie and the last one, I wondered if the guys who wrote the movie and came up with some ideas for the movies actually ever READ the comic books. It appears that the writers spent considerable time reading the Wolverine comics and graphic novels because they really get into his past in the second movie and go on about his mysterious past and so forth.
Let's start with Jean Grey.
In the comic, she was in space trying to pilot a ship and went through a star burst or something and the ship crashed and everyone thought she was dead. Then, this character, Phoenix appeared with all this power and everyone thought the Phoenix was Jean Grey reincarnated but it wasn't. It was actually an alien force. The Phoenix then posesses Madelyne Prior who is the clone of Jean Grey and Cyclops falls in love with her and they have a child. Then there are some alternate universes and alternate futures where their child comes from the future and blah blah blah. The Beast creates something that supresses the power of the Phoenix. Wolverine stabs her...blah blah blah. The Phoenix then goes back to Jean Grey who has been hybernating all this time in a cocoon and she accepts the Phoenix force and is resurrected and her and Scott get back together and the resurrected Prior kills herself and uhhh...well basically blah blah blah. Jean is eventually separated from the Phoenix and the Phoenix is destroyed by some aliens and Jean is happy go lucky again. Yay.
As you can see, this is a very complicated storyline. The reason for this is that about a dozen different writers had their opinions of which direction the story should go. Most of them were wrong and they sucked and should be kicked in the balls. Inferno was one of the best story lines ever in X-Men IMO. Very complicated and hard to keep up with at times. Good cross overs and so forth though.
In the MOVIE with Jean Grey, she is thought to be killed by a bunch of water when she is trying to save everyone on the plane. She eventually gives up and basically kills herself by giving up. Of course we come to find out that she didn't die, but that her unconscience, much more powerful, mind protected her and kept her safe and kept calling for Scott. When he shows up, Jean, in the form of the Phoenix, comes out of the water and tells him to take his glasses off. He does and she controls his power. They kiss and make out and then suddenly they show Xavier having some problems and he tells the X-men "Get to Alkali Lake". They go there and everything is floating around. Wolverine finds Scott's glasses floating there. It's never said, but it's assumed that she killed Scott. Ok you're going to kill Cyclops in the first 5 minutes of the movie. Fine. He's one of my favorite X-Men characters ever and now he's just dead. Ok you see the problem is that in the Dark Phoenix Saga, she never kills Scott. She kills alot of people and even destroys an entire planet before killing herself (not permenantly of course) to stop herself from killing anymore. Blah blah blah. Then, they never even mention Scott for the rest of the movie.
They take Jean back to the Mansion where she breaks out and goes back to her home where she grew up. At the Mansion, Xavier explains that the Phoenix is a subconscience entity that he himself created by supressing Jean's powers by putting locks on her mind to prevent the darker more powerful side of her to be allowed into her conscience mind. Ok so in the comic it's an alien entity. In the movie it's just supressed power and rage. Whatever...you guys are stupid. Then, when Xavier and Magneto show up at her house, JEAN KILLS XAVIER by ripping him apart at the molecular level. He pretty much just disintigrates and there's nothing he can do about it. He looks over at Wolverine who is floating nearby and smiles just before he explodes. Strange eh....
Let's recap. You've killed Cyclops and Xavier and only about 25 minutes have gone by so far.
Then, there is this mutant who's power is that he can nullify other mutant's powers when they are near him. In one scene in particular, Juggernaut runs toward the boy with the power and the Juggernaut's powers are nullified. The problem with this is that the Juggernaut isn't a mutant but rather his powers were given to him by a mysterious gem AND the Juggernaut is Xavier's step brother.
Basically, if you have followed the X-men comic books, you will find alot of inconsistencies in this movie and you might find yourself upset and pissed off that the writers of the movie apparently have never read the comic books. It appears once again that they really read through alot of Wolverine books but just skimmed through some of the stuff in the X-Men books.
Seriously, they are just NOW having Angel show up. We all know that Angel was one of the original X-Men. He barely has a part in this 3rd movie finally.
I full well understand that in the making of a movie adaption from a comic book, you are going to have to make some fundamental changes in the story line and and make some minor detail changes, but this movie was just a complete rewrite and they made HUGE changes such as the death of Scott and Professor X. You got Patrick Steward to play Professor X then you're just going to kill him off? Who's idea was THAT? I mean damn. After watching this movie I was hoping I would wake up and be ready to watch the REAL X-Men Last Stand movie.
A couple other notes of interest:
The "cure" that some of the mutants in the movie got is not permenant which is evident by the end scene of Magneto starting to be able to use his powers again while he's playing chess by himself. Or is he playing by himself? That's another point.
Remember the scene where Moira is there with a man who is a patient of hers who has no mind at all and the lesson in the class talks about the possibility of moving the mind energy of one person to another person. Well, if you stick around after the final credits there is a scene where that man with no mind suddenly wakes up and looks at Moira and says in Professor X's voice "Hello Moira". DUN DUN DUNNN!!!
On another note, neither Cyclops or Jean is dead either. I expect to see Mr. Sinister in the 4th movie FYI...
I highly recommend that everyone go watch this movie and then you too can get pissed off about the inacurracies or you can just not give a shit because you're not a comic book geek. Have fun!
