No, this thread is not for one to discuss one's opinions on this subject. There are no more opinions. There is an objectively greatest movie ever.
This is it.
I especially like how the shark eats a US Navy Cruiser, and eats the Golden Gate Bridge, then tops it by eating a passenger jet (Which appears, when the dude looks out the window, to be cruising at a cool and breezy 150 feet). Also the giant octopus crushes an entire oil rig and then smacks a jet fighter out of the sky.
But do not fret! Whilst the time-honored question of best movie ever may be answered, I'm sure we can instead discuss the greatest moments in this movie, or indeed just the trailer.
I think I like the dude at 0:32 the most.
