I hate 3, Resurrection, Prometheus, and I never saw AvPR or Covenant. I think my gut feeling is that 3 is the most frustrating entry because it takes a great movie (Aliens) and completely ruins the ending of it by killing off every single surviving character. It also does so in a way that makes NO SENSE (seriously Google the massive amount of fan arguments and retcons that attempt to explain how that egg got on that ship and how many there were. There straight-up is no good explanation.) The only way I can enjoy that ending now is pretending 3 doesn't exist, so that's what I do.

Resurrections requires me to already accept 3, and by contrast it's much stupider and on paper it's the worse movie, but it's less aggravating because at least it doesn't really fuck up anything that I care about. So I hate it way less than 3.

Prometheus is just a dumb movie. I don't particularly like any part of it, it billed itself as a prequel to Alien and yet has basically nothing to do with it, doesn't explain where the Aliens come from, doesn't explain really why the Engineers are evil bastards, and every character is a complete imbecile. I was genuinely confused by the positive reviews after I watched it.

AvP on the other hand...is dumb fun. The fact that it's not canon anymore makes it easier to swallow as an entry in the series. Turn your brain off and it's enjoyable.
