So...which Marvel superheroes have worked best as movie characters?

[Spider-Vader]

Iron Man definitely.

It shows too, why else has the character jumped into the spot of Marvel's second biggest character?

Take out Nightcrawler, and I agree with your list, and I'd probably add Tony Stark. I'm not a fan of the Iron Man movies, but I must say that Robert Downey Jr. did a fine job.
