A friend of mine wanted to marathon the Alien franchise, so we watched Alien, Aliens, & Alien 3 on Saturday evening. He passed out mid-way through Alien 3. I would've kept trekking right on to Alien Resurrection otherwise. It was his own foolish idea to make it a drinking game. We kept it simple however, as I had learned my lesson from a previous experience. I hadn't watched any of them all that recently. I've always proclaimed that Alien is my favorite, though really Alien & Aliens are both neck & neck. Both marvelous. 2 of my favorite movies of all time. I'll always go to bat for Alien 3, as many on these forums would. It's not that far of a drop off in my opinion. I'm trying to talk him into another triple feature of A:R & both AVP films. Sadly, he's not as eager to oblige.
