Thankfully, it isn't exactly like "Contact". It is a decent film, but I would say that the film is more about interaction with the aliens, how language works, and concepts of the fluidity of time rather than a sci-fi action film. I liked the movie, but keep in mind that it is a bit more of a high concept film than it is a summer blockbuster film. My only "criticisms" of the film would be that the ending is a bit abrupt and that it could have used a bit more backstory and resolution in regards to the aliens.
Frankly, it sounds like an anti-climactic Stephen King book/film. Disappointing or unfulfilling ending - hurried and rushed.
