The X-Men films were always more about Wolverine. So other story lines were changed or diminished as a result. While Marvel will be agreeable on furthering the Hugh Jackman-portrayed Wolverine story (which they are), they will never do a Famke Jannsen Jean Grey/Phoenix film.
Not on it's own, but I'd suspect they would do one (or at least be open to the possibility of doing one) in the confines of a Wolverine movie, which would be fine by me.
I didnt think either were "botched" paticularly. But I do prefer the Phoenix one and found that the Venom would have been better being the sole focus of the film, rather than how it ended up, so I voted Venom.
