The gf and I watched them all in the last three days. No (major) spoilers. My list.
1.Predator: duh
2.Predators: This one was better than I remembered. I'd say it's almost even with Prey but I found it a little more entertaining and it introduced the different Predator factions. (This was my gfs favorite one)
3.Prey: Pretty good once you get past all the people speaking English but somehow not understanding each other. I guess there is a dubbed version but I didn't see that one.
4.Predator 2: I really wanted to rank this one higher because I loved it as a kid but it hasn't aged as well as I would have liked. It still has one of the best endings in any movie imo. (This was the gfs least favorite)
5.Alien vs Predator: This one is oddly rewatchable. Has some dumb moments but overall I like it. When I realized the chick was the same one from Blade... mindblown.gif
6.Alien vs Predator Requiem: This one wasn't as bad as I remember but the whole alien Predator Hybrid thing was dumb and kind of doesn't make sense. This movie was also DARK and not in a good way I mean I had to turn the brightness on my tv way up to see anything.
7. The Predator: Maybe they could have had a decent movie here if it wasn't for the over the top cringe inducing dialogue throughout. It was just awful.
