Leading character is much more than a student who is obsessed with UFO sightings. His determination is really inspiring. But not enough to make this movie more than 2 stars. I've got to tell that "Arrival" was a complete satisfaction for me so I don't think I can like any other movies in similar fiction.
Sure this is not the next greatest sci-fi drama, but I thought it was solid enough - mainly due to its concept. Plus, it's always interesting to watch the (eternal) Agent Scully in another extraterrestrial universe.
