What if Earth were to develop a team made up of Marvel's most popular characters? That would be so crazy. Possible names include: WOLVERINE and The Avengers, Ironman's Uncanny Avenger Force, Spiderman and his Amazing Avengers.
This Daredevil story would stand on it's own I think, like the Punisher movies. It's hard to determine how good it would turn out based solely on this video, but I think it has potential. I suppose Carnahan could also just make this movie and turn the daredevil character into some other super powered or in some other way significant protagonist. With Daredevil and Murdock's focus on enforcing the law and stopping criminals in the comic books, a film with the general feel of this trailer could definitely fit.
Marvel has done quite well producing movies (with the exception of The Punisher films---all of them) so I'm expecting The Avengers to be enjoyable when I finally get to see it. Can't really say the same for DC. Burton and Nolan's first Batman films were good and that's about it. DC has long depended too much on Batman and Superman. It is promising to finally see a Green Lantern film though.
