Knight and Day is in the same league for me. Complete switch you brain off, silly, ott action.
(please also see Spy, Central Intelligence and The Heat)
Funny though (and just thought of this), in all this "if you don't like female driven films you are a horrible man" drivel that the people keep spouting about recently, only one has no female leads. I make it pretty much in favour of women. Who would have thought that great scripts and good acting will win out.
