I don't think I've ever seen the movie, though I'm not ruling out having rented it as a tween back in the day and forgotten about it, but what's with the weird video compression artifacts that move with their faces, like how Siskel looks like he has a chunk missing from the left side of his nose in the intro or that brown stain that appears on Ebert's forehead around 2:36?
It's exactly the sort of unnerving compression artifacts that end up in kooky conspiritard celebrity Reptilian "proof" videos.
I like Aliens more than Gene Siskel did but I can understand that it's not everyone's cup of tea, it's quite an endurance ride if you're not that fond of space creatures in claustrophobic, dimly-lit, exo-solar moon colony corridors.
I like Aliens but don't love it, it's like maybe a top 5 of 1986 film for me but below at least both Ferris Bueller's Day Off and Project A-Ko.
From Beyond is a better movie, even if you go by the standard that at least it's not directed by James Cameron - it's hard not to see the various meathead-isms of Cameron's oeuvre embedded throughout Aliens that would blossom more fully in future efforts including 'Avatar'.
