Mission Impossible 2 seemed like the producers came up with the action sequences before they had any idea for a story (imagine some producer writing on a napkin: MEN ON BIKES JUMP OFF THEM AND THEN COLLIDE IN MIDAIR!!) Then they hired the screenwriter to come up with some half-assed way to stitch them together.
MI1 had an excellent screenplay, though.
