The thing I like best about tribute acts is, it's all the songs you know but sometimes in a different order. I'd certainly recommend it if you have never seen an Alien movie as this way you can see ALL THE ALIEN MOVIES.
In One Place!
Weirdly that still makes it the third best of the Alien movies.
Naturally, with Alien almost fifty years ago. things are faster this time around. No pesky scenes of discussion needed... ugh those scenes were so boring in original Alien what with its slow building menace and naturalistic dialogue. It would be infinitely better to speed up that totally unrealistic life cycle. Speed that puppy up buddy - thought not like the Alien 3 puppy. Bad puppy. No biscuit.
The best alien movie for me continues to be Alien. Followed by Alien: Isolation. Still, watching Sailor Twist in your local pub function room may well get you singing along with her rendition of Fearless.
