What is your favorit Aliens movie? I like Aliens (Alien 2) Because of all the nice characthers that was created in that movie, it was also one of the greatest sequels of all time.

Do you mean any movie with an alien in it or just the Alien series?

Alien

Aliens 2

 imo aliens was the best as it had a good balance of action and suspense but alien was good though.

Aliens. The other ones after that were alright, but also really unnecessary. 

Psh, I think everyone's forgetting about AVP2.

I'll go with Alien, more horror and less action 

@ARMIV: I was pissed when they built up the kids character in Aliens. And then in Aliens 3 she died in the intro.

The first one was the best by far.

But none of them until AVP2, were "bad". Maybe in comparison to the other films in the series, they may have been "bad". But Not in terms of cinema as a whole.

I was actually surprised by how much i enjoyed resurrection (4), maybe because i'm a pretty big ron perlman fan, but my favourite is still the first one.

Mac And Me

1. Aliens (2)
2. Alien
3. Alien 3
4. Alien Resurrection
5. Alien vs. Predator 2
6. Alien vs. Predator

Alien.

I'd probably say Aliens and then Alien Resurrection since I'm a big Joss Whedon fan. I also think that Alien 3 was underrated by many people but still probably not as good as Alien. All four of the main Alien movies were better than the Alien vs Predator movies.

Whenever there is a good movie, with a good sequel I tend to defer to the original.............

Species.

Star Wars!

to my regret ive never gotten around to actually watching 1 or 3. but i love Aliens

I personally like Alens most. (The second movie)

One of the few truely "alien" aliens in movies.

1. Aliens (virtually flawless sci-fi action)
2. Alien (horror done so well)
3. Prometheus (flawed but loved it)
4. Alien 3 (gets more hate than it deserves IMHO)
5. AvP (ehhh popcorn fun to some degree)
6. AvP2 (WHO TURNED OFF THE LIGHTS?)
7. Alien: Resurrection (Whedon wrote this? You're kidding, right? ....right?)
