An Honest Review
1 April 2017 | by (United States) – See all my reviews

This one hurt a bit.

I mean, there were jokes that made the whole movie worth watching. Unfortunately those jokes weren't enough to really break the Alien thing.

Watching it I wanted the return of the masks, at least then it wouldn't have hurt so bad after the first two.

Instead we had introduced dead-end characters that we meaningless at the end, no real advancement, and a plot that was trying far too hard to be science fiction and not nearly hard enough to be Scooby Doo.
