Resurrection is a movie I have not watched again pretty much since it came out. I bought the big flashy DVD and Blu-ray boxsets and still haven't watch A:R or the extras. I just didn't like the pace or the story itself, and the characters were great but really felt like they didn't belong in an Alien movie. As strange as it sounds, if the film had been it's own thing and not connected to the Alien mythology I probably would have enjoyed it more.
Prometheus and Covenant would have made the list but I try not to look at them as Alien movies but rather lacklustre attempts to tell a grandiose story - luckily, I had inside skinny on the production so I kind of knew what to expect. My main problem is that the characters in these movies made dumb decisions, and for a bunch of supposedly smart scientists that was really grating. Other than that I find them watchable as visually they're pretty good and I've got a soft spot for concept and design.
I love Aliens, it's a got-to action movie of mine that I can watch again and again, but I have a long list of issues with it that have only hit me in the last few years. I'll share that at some point.
