My opinion on this movie is its just ok (NON SPOILERS)
Now the first 30-40 minutes of this movie drags because of character development which shows really nothing for our characters.
The middle of this movie was fun yet had some stupid character choices, for instance if you get bitten by a alien then logically you should be in a vaccination area but in this movie the character choices are stupid.
The ending was pretty good due to the alien design which looks really cool!
Overall: 7.2/10 (first part drags, characters dont really matter too much, ending is the best part, cliche plot, had some really good scenes, had bad character choices)
