Re: AVENGERS: Grade, Reviews, Discuss, DVD & Sequel **SPOILERS**
I listened to this part of the commentary
All script weaknesses are duly noted: Whedon himself wasn’t a fan of how the Chitauri basically “had their strings cut” once the mothership was blown up, but it had to be done to prevent the battle sequence from continuing.
Joss also didn't want the Avengers to do clean up for 17 hours
"Inception" is a layer cake.
