I'm 49 and saw this with my teenage kids and I must say, I enjoyed this as much as they did. If you're expecting a huge Hollywood blockbuster production, this isn't it, but it was still a surprisingly very well produced overall low budget B-film. It was very well directed and fairly decently written - aside from a few plot holes and issues. The cast were all excellent and convincing in their roles. The cinematography was on point, and what little SFX there was, it was done professionally, not cheesy like some recent sci-fi's I've seen. This is a fun and entertaining film for the entire family. It certainly leaves the door open for a sequel, and I hope they do make one. A well deserved 7.5 rounded up to an 8/10 from me.
