I really enjoyed this movie, it has good funny moments, and not a grotesc humor that sometimes they use to mock the whole concept of aliens. I don't believe in aliens myself but I don't like to make fun of other people beliefs. Acting is really good. Overall satisfying, if you want to have a good time without nudity and/or violence, this is the right movie. I don't know why the low rating, people give high ratings to movies with known actors, many of those movies I don't enjoy at all, full of vulgarity, cursing, nudity and violence, always giving bad teachings, mocking of vegetarians, protestants and virgin people, yeah that's Hollywood unfortunately, I am all those things and I proudly say it. So yes this movie is very enjoyable, well done!
