This is sure to be a controversial point, but it's plainly true. Though there are lots of good jokes scattered throughout this flick (essentially a "sci-fi comedy"), there are heaps of gags that don't quite work; either the timing is off - due to editing - or something else is going on that distracts from the moment, like an action scene or a musical cue. That's not to say Guardians is "unfunny" - just that the humour doesn't feel honed. In a way, Guardians recalls another good movie that was only half successful in its comic intentions: Edgar Wright's Scott Pilgrim Vs. The World. In a similar way, jokes fumbled due to the editing, or because the actors unleashing said jokes seemed unsure of how to deliver them. It's not a monumental issue, but there are a healthy number of noticeably awkward moments in Guardians where the funnies don't hit their marks.
