Yeah, the amnesia bit is not believable, but this is a movie, right? The bottom line is the acting was awesome, the leads totally nailed it. Without their spot on acting this really could have gone off the rails. And, most of all, even though I watched this on a plane from Taipei to Osaka, I laughed a lot! And practically nothing makes me laugh these days, so the writers really did their job. I will have to get my wife to watch this (she was watching something else on the plane).

So, as far as the negative reviews, I guess those folks have even less of a sense of humor than I do :-). Just give it a try. I think most people will really enjoy it. Just relax, suspend belief, and prepare for a wild ride.

BTW, some people said it was predictable. But one aspect of this that got me laughing was some of the comedic bits took me completely by surprise. Like, what the heck? LOL!
