The acting and conflicts weren't even realistic. The villian is a stereotype monster, down to the sounds and behaviors. Basically take the sentinel from the matrix, put it on a body like the predator and make it walk around and have behavior like a xenomorph, chirps,clicks, and everything.
The time travel plot of this doesn't make sense, they travel into the past and say "ill leave this here for a billion years and they'll have the fix", but when they flash foward, it's like the person they left remembers exactly who they are. It's not a logical movie, and i rewatched the last parts and still dont make sense of it.
