Okay...
I fear we don't seek the same qualities in actors.
What actors of the X-men franchise (or even MCU) do you deem as being good ?
(I feel I blamed the actor unnecessarily. He did not rewrite his character.)
Hugh Jackman has been appealing enough. He's a good actor, and he's done what he could to be Wolverine.
I loved James Marsden. I understand he wasn't very happy with the way his character was portrayed and I can hardly blame him. Its very sweet how he's trying to protect the new Cyclops.
I think Patrick Stewart made a good modern Xavier. One of the long-time X-men writers felt he was too soft and sweet, that a Yul Brynner type would have been more accurate. That's very true of the old characterization. More modern characterizations have been kinder, and its with good reason most people wanted Stewart to play him.
Magneto's personality has been all over the map in canon. Claremont hinted that that may be because of his powers affecting..something in his physicality. Both actors portraying him have done wonderfully, whatever personality he's given. That line, "Are you sure you saw what you saw?", still makes me cringe, unfortunately.
Rebecca Romijn did a surprising good job as Mystique. Her cynicism and coldblooded nastiness evoked the real character. Would've preferred to see her acting as the independent leader she is, than Magneto's toady, though.
I liked the guy who played Gambit in Origins. Very good cute *******.
Ryan Reynold's Deadpool was adequate. I expect he'll do okay in the upcoming movie.
Iceman seemed accurate enough. Vaguely hostile, dorky, emotions on his sleeve, not the brightest, always attracted to the wrong girl.. Singer joked that there might be something meta in dating the girl he can't touch and a girl with occasional touch issues. Not great, but I have no bad feelings about him. Really hate his beard though.
I know nothing about John Wraith's character, but Will i Am was very charismatic in the role. Wish we could get more of him.
Peter Dinklage made me love a character I'd only hated before. Very uncomfortable.
I only hate Rose Byrne because it isn't that hard to get a Scottish actress. Another decent actor, screwed by bad writing.
I find Angel Salvadore to be repellent in comics, but in movies, she wasn't bad. Her characterization seemed very believable. One of the few improvements.
Oliver Platt's g-man made me cheer. Along with his humor and general flexibility, I immediately fan-canoned that he's related to Patton Oswalt's Agents of Shield triplets characters.
Eva Magyar seemed believable in her role as Maggie's mom. She reminded me of artwork of Magda, Magneto's wife.
Bruce Davison was never more appealing than when he was dying as Robert Kelly.
There are actors like Alan Cumming and Kelsey Grammer that I like in other roles, but did not like their portrayals here. I'd blame the writing. I want to like Famke Janssen but...I don't know. I'm not sure if it was bad writing or lack of magnetism.
