Avengers was great, but some bits of it felt shallow like a big block buster with lots of funny explosions.
At the end of Avengers it would have been better if Tony failed with the Nuke
Not in NYC, but after going through the portal....Boooooom! and then dimensional door closes
The movie would have been smarter if Tony remained stuck on the other side in space
Thanos and whatever chitauri is alive then pick up the battered Ironman, capture him, torture him.....Thanos and Ironman....perfect and in comic book continuity
