The movie open with some CGI of alien creatures running around on what I think is supposed to be an alien planet. The CGI aliens are not terrible for a low budget movie but they show them onscreen way, way too much. Then it cuts to a technician warning of impending catastrophe with a rift that the base is built around. Apparently, there's an Area 51 in the UK or it's in the UK in this universe or something. The aliens from the beginning start busting through the rift and overrun the place almost instantly since their security is a few guys with rifles. From there, the movie just sort of stumbles from one scene to another without a lot of rhyme or reason. It lurches from one cliche thing to another like the filmmakers had a premise but no idea where to go with it. There are a lot of "because movie" moments where character do stupid or nonsensical things because the movie needs them to. It's not the worst thing I have ever seen but it's not really worth watching either.
