Can i watch a movie online?

first off, i know it's illegal to bootleg movies and distribute them all over the net. second, it's also illegal to hack into companies protected files and download that. let it be known, i'm pretty much technology illiterate. if i google "free online movies", about a thousand sites are available, i pick one and watch a movie without downloading anything, am i in trouble? also, let me know if i'm in the right category for this particular question. thank you to all.
