Yes certinly rate the X-Men movies, and the Spider-Man films. Not so keen on the reboot of Spider-Man though.RotLA is one of the best adventure films of our time.
Regarding comic to movie conversions, while I agree the over doing reboots diminishes the brand (in most cases Marvel), some of the early movies are excellent and can't be replaced as I think of X-Men 1&2, Spider-Man 1&2, X-Men Origins:Wolverine, Hellboy (Darkhorse), Men in Black, Ironman, and V for Vendetta. My disclaimer is that I'm judging these stories as movies and not how faithful they were to the original content.
Ironman's okay, but I find they all merge into one.
