Prometheus would probably be the natural next choice. It’s decent enough - better than Resurrection for sure - just don’t expect it to live up to the original. The assembly cut of Alien³ is an improvement on the original release imo, so if you already like that film you might enjoy the comparison.
If you’ve got something to play games on, Alien: Isolation is actually your best option though.
Prometheus is fiiiine, I thought it was okay, did not like covenant. To be honest they should have stopped going back to the well after alien 3. But if the first 2 films nail a sci fi horror and sci fi action film pretty much better than anything else there has ever been then it’s always going to be a case of diminishing returns.
And i hate to say it… I’ve lost my respect for you.
Saw prometheus at the cinema and it was a generous 2 out of 5. The other one was about the same except i forgot every bit of it, apart from daft flute nonsense, as soon as it finished.
