I'm sorry but this entire genre would have serious lack of cool issues without Robert Downey Jr. and Hugh Jackman heading up both successful heads of the Marvel film transition.
I say successful because its not like Thor was any good in fact it was an over marketed piece of crap that probably cost more than it made at the box office or even in DVD sales. Captain America and The Hulk both suffered from effectively the same problems and B grade actors that Thor did.
Of the X-Men films, to be frank, only X-Men: Origins (Wolverine), could be considered even acceptably good (Even Sir Patrick Stewart can't save some things) and that was because Hugh Jackman was BORN to play James Howlett/Logan. Hugh Jackman isn't even what I'd call a GOOD actor, hes just an INCREDIBLE Wolverine which makes up the difference. Conversely Ryan Reynolds was hardly born to play Deadpool, Taylor Kitsch was the dumbest vision of Gambit I've ever seen.
The stunning stand out in this entire comic to film transition truly is Robert Downey Jr's rendition of Tony Stark and to be honest I wouldn't even say that Robert Downey Jr's Tony Stark even fits the canon Tony Stark but its just so neurotically cool that its fun to watch. The whole Iron Man thing is just the icing on the cake in the case of the Iron Man franchise, its Downey's acting and his presentation of what a modern era Tony Stark would be is what makes it so good.
DC Universe? Superman hasn't worked seriously since probably the first movie Christopher Reeves did...and again its because you had an actor that was born for the role. Batman? Christian Bale has not been all that convincing, he works in the suit, but then again so did Michael Keaton, if a suit can make Michael Keaton a super hero its not that hard to take someone as unexpressively boring as Christian Bale and do pretty much the same thing. Christian Bale's Bruce Wayne is generic, uninteresting, patchwork GQ billionaire personified with very little actual character behind the character beyond the canon events of Bruce Wayne's life. To be frank the entire Batman franchise since Bale put on the mask has only truly stood out due to Heath Ledgers Joker...which was probably the most incredible filtering and purification of what the "Joker" would truly be in a more "real" world than a comic. It was Heath Ledger that made the Dark Knight, not the Dark Knight himself. To be frank, take anyone you want, and put them around all that high tech CGI and movie model work and they could probably do the same job Christian Bale has done in regards to elevating that franchise....which is little to none.
Simple facts are I'm not tired of super hero movies, I'm tired of super heroes being portrayed by actors who can't do anything with the roles other than "play" the part.
Hugh Jackman as Wolverine is much the same as Christopher Reeves was to Superman, so perfectly designed to BE that character that you simply associate them WITH that character for the rest of time. And Robert Downey Jr. IS the cool factor of the Iron Man franchise, sure the CGI is fantastic, but without Downey's vision of Tony Stark, Iron Man would probably have turned up quite a bit like Thor did. With some barely passable actor that could vaguely appear to be the primary protagonist. (Lets face it, Thor was not a tall skinny rocker dude, not in any vision of the character. And Thor vs Hulk was one of the greatest hero vs hero rivalries of ALL time in the early Marvel Universe) and while their CGI Hulk is pretty good, I'm never going to believe the rivalry between this skinny long haired C movie actor and their CGI Hulk, that they attempted to allude to in The Avengers...it'll be about as good as...well, Thor was, which was, really, bad.
So yeah, more movies, less badly cast actors please.
