The negative reviews were left by arachnophobes and should be discounted
Seriously though, this film is amazing and I was surprised by how much sense it made given how complex it seemed at first. I went into it with no expectations, aside from seeing that Adam Sandler played the main character (he crushes it in more serious roles). Definitely not your typical sci-fi space adventure, and that’s very refreshing. If you want to watch something introspective and visually interesting, this is a great watch.
