As opposed to watching other marvel movies first so as to understand what's actually going on. And also, you know, just watching it for some cheap thrills. I hate people like that.
Oh, yeah, no that's fine. You need just enough to understand and it won't hurt you to skip some of the earlier movies. The two avengers movies pre-infinity wra are musts, guardians is a must, ragnarok is a must. Civil war is definitely a must because everything spreads out from there. It wouldn't hurt to watch winter soilder but, eh, not really that nessesary.
