Silly is fine with me, the franchise was born from 80s cheese. With Black at the helm I expected some cheesy jokes anyways, his humor is unique though. The common praise is going towards the cast, gore, and humor. Some have mentioned oddly edited action which worries me but others say it's got good action. These twitter reactions are always hard to go off of!
Also it appears that they're is either a mid or post credits scene. Two people have referenced a coda.
