Would be 3.5 but have to dock it for that dumbass final scene.
Otherwise this is a solid sequel and the decline in quality is nowhere near as steep as the ratings suggest.
Also it's so goopy! Splatter and monster drool and monster poop and
Watching with an eight year old who can't remember who is who without costumes ("Is that Captain America?" - what he asked when Tony was talking to Scott at The Raft) is an experience I do not recommend to anyone.
Still good though. Even if Falcon and Soldier did Zemo and Sharon dirty.
