I've been a slobbering Alien fanatic since age six, and Aliens made its theatrical debut. Mmm, I can still recall the thrill of every slapped ammunition clip, every morbid hiss and the wicked cacaphony of machine gun fire.
Anyway, personally, I bought this because - well duh - its the Alien series. The pros are that I have my prized DVD collection in a nice little box. The cons are that it came packaged with a lump of [poo] called Alien: Resurrection. Personally, I've always looked down on people for their dim view on Alien 3. It made a perfect circle, I thought, to the series. Everything was fairly nicely wrapped up in an intriguing and fittingly depressing conclusion. The fourth film, however, was such a pathetic attempt I wish it hadn't been made. The impressive cast aside (although it certainly wasn't Ron Perlman's pinnacle as an actor. "So, like, what'd you do?") there were very few saving graces, and Buffy's Joss Whedon needs to check his head if he even thinks for a second that he's ever going to be Aliens material. He needs to stick where he belongs: television.
Anyway, given that this is only the price of 3 DVDs, you're basically getting the fourth one for free, so I strongly suggest it, just as I strongly suggest burning the fourth installment and sending it to Joss Whedon with a picture of his dog being sodomized by a kimodo dragon.
