I love Alien so much I can't help watching all the terrible Z-grade knockoffs, and honestly, I enjoy these too because they show you why Alien is so good. You can see how Alien took the same kind of material but elevated it through high-class cinematography, breathtaking sets, the involvement of a real artist designing the monster in the form of H.R. Giger, excellent writing, the best cast you could hope for, etc. A lot of that does come down to the budget since millions of dollars allows you to get better actors, experienced craftsmen, more time for shooting, etc. so I still appreciate these down and dirty clones but the true flaw of these imitations is not being original. But like I said, I still love to watch them, and they usually have some well-done moments at least or they'll make you laugh. Inseminoid is pretty bad but it gets pretty crazy and fun around 32 min in. If you click here, you can watch it for free on Tubi right now (in the US at least). I really love the posters for it below.
