New Avengers Trailer: I knew there was some reason for the Thor and Captain America movies

Not that the movies were really bad, but didn't anyone else leave the theaters with an empty feeling after seeing that both Thor and Captain America had little more value than being Avengers prequels? Perhaps it was just me, but I had the same gnawing regret about buying tickets to see them as I had when I saw X-men Origins: Wolverine-- except the Avenger Origins movies were an honest to goodness bait-n-switch. Now that's not fair Paramount-- if I had wanted your ugly friend, I would have spent my money on that creature and not on your fine promises.
