The Returner

Basically a cross between Terminator and E.T.—no, wait, make that a rip-off of Terminator and E.T.—this film is about a warrior who travels back in time to stop alien robots from destroying the Earth. Teaming up with an assassin, she goes around blowing stuff up and making friends with ugly-cute space aliens who just want hugs. You could pretty much make this film yourself by just taking a dozen sci-fi action films, cutting them into pieces, tossing the pieces into the air and reassembling them at random.
