Chad R said something that really resonated with me at the last T-Fest. He said when he looked at monster films to watch on Amazon Prime the first thing he did was check when it was made. If it was made after the ’90s, it was skippable, since the vast majority of those are generally on the level of SYFY “Original Movies.” I agree enthusiastically, because I do the exact same thing.
That said (and I haven’t checked to see if it’s on Amazon or YouTube), Unseen Evil 2, aka Alien 3000, aka The Unbelievable 2, was made in the 2000s but at least has a monster suit. I don’t think the first one does. The monster has convenient and cheap Predator powers, and thus is mostly economically invisible. The trailer for the first film suggests that the sparse looks we get at the actual monsters are the horrible CGI you’d expect. Ditto for the second film, although again, they do seem to have built or rented an actual suit so the monster could actually interact with the actors. I’m not sure that means it’s better, but a suit is always more entertaining.
