good horror, poor sci-fi

Rating: 8/10 (2 June 2017)

If you are looking for a great sci-fi film you better stay away from that flick. Surely not the best sci-fi because there are too many logic errors that you just can't miss them.
But it is a great horror film with Kalvin the alien neutralizing everything on its way.
The best in the film is that this alien is evil as hell! That thing is really thirsty for blood!
I will probably watch it again someday.
