As a big sci-fi fan and UFO-enthusiast, I really recommend watching this film. Even though I watch a lot of movies, I was a bit discouraged watching it because of the '4/10' rating. But unlike what many people here wrote... This movie did not disappoint me in any possible way. It has a great build-up, strong climax and mind-challenging ending. The constant suspense (after the introductions), no obvious scientific 'mistakes', some good jokes at the right times and zero jokes in serious/tense moments. The acting, the story, It all felt very credible to me. Bottom line: If you like the Area 51 mystery, give the movie a chance and the credit it deserves. Don't always rely on IMDb/'critic' ratings. I was physically ill after watching Gravity. If you agree with me on that part, I think you'll be safe watching this movie! Also, If you enjoyed the movie "as above, so below", you're quite certain to enjoy this.
