I agree with pretty much all of that.
I think Alien is very good but I also think it’s a touch overrated. I also think Alien 3 is underrated (especially the superior Assembly Cut) and Prometheus is underrated (especially Agent 9’s fanedit). Have not seen Covenant yet, and Resurrection is silly nonsense (although it has a few cool things going for it).
I don’t count any of the AvP movies because I just can’t possibly care.
To bring it all back to the beginning, I guess I can understand not liking Aliens although it still seems odd to me…but to say you wish you could unsee it makes no sense to me at all.
