Julius Kassendorf’s review published on Letterboxd:
Leprechaun Goes to Space
Make no bones about it, quality-wise this is sub-Canadian sci-fi television. Bad acting, flat cinematography? And semi-cheap sets.
But we're not here for production values, we're here for bad dialogue, insane plots, horrific jokes and general WTFness. It delivers this in spades. The frame rips off Alien, but also The Fly and those 1950s embiggening movies. There's also a space princess and hypnotizing breasts and...it's really all thrown in with no regard for logic or sanity.
Really, though, isn't that what we want from a movie called Leprechaun 4: In Space?
