Prey was pretty alright, especially after the slew of Predator-related dogwater that came out before it.
The setting was cool, the visuals were cool, the action was cool. Yeah yeah it has an 80 pound girl beating the shit out of 200 pound soldiers but the movie kinda tries to make it somewhat believable because she uses tools, fights dirty, etc. The final fight against the Predator is a bit anti-climactic with a huge case of plot armor but let's not pretend Dutch isn't covered in tripple-layered plot armor in the original.
It's a perfectly fine movie.
