What scenes did the audiences you were with react to best?
Pretty much every Hulk scene
Hulk Smash.
When banner said "I'm always angry, that's my secret" and then 1 punch KO that dragon thing.
When Hulk thrashed Loki around and called him a puny God.
When Hulk punched Thor off-screen.
There were so many great and funny moments though. Would be impossible for me to list them all.
