I'm a (long) lifelong sci-fi film lover and I'm fairly literate on physics, astronomy, etc. but definitely NOT a scientist nor do I have a related background. That said, I found this film way over it's head for any normal audience. Perhaps utilizing some aspects of gravity unknowns, or black holes, or wormholes, or multiple dimensions, or time travel, or climate messages would have piqued my interest but using ALL of them in one film only confused an already confused film. "Contact" fans know well the term 'Occam's Razor' and I find it appropriate for this film. Just keep it simple! You can still make an intelligent film, complete with a great script and special effects..without thinking it has to have everything including the kitchen sink. Ironically, that term in Contact was first voiced by Matthew McConaughey. I was severely disappointed in the film, not one I will add to my library. Great special effects, that's about it.
