Don't the movies usually screw up the comics? I did not read the Avengers, but I read League of Extraordinary Gentlemen and Watchmen, and those movies not were inferior, but in the case of the former, sucked really hard and were grossly unfaithful to the source material. Kind of like Van Helsing. Teaming up heroes or other seperate characters "just because" doesn't work in Hollywood. Or rather, they make a lot of money on hype and undiscerning kids and then the foreign markets, where the dialogue and characterization don't matter. If movies can fail with widely known characters like Dr. Jekyll, Dracula, Captain Nemo, etc. how much worse will they do with characters who are much more of a niche fandom?
