I like watching From the blind Chinese ping pong master to the slightly camp Christopher Walken who plays Feng. A crime lord who takes fashion lessons from Elton John. I have to say, I've never seen such a glamourous side to ping pong.
Completely outrageous, it has some soft satire on stereotypes who play in the ultimate competition of sudden death (quite literally!). The evil blonde hair blue eyed German, the knife wielding Japanese and the basketball player look-a-like Canadian! It is again, your harmless teenage slapstick humour. So if you know you don't like that style...I suggest you avoid it. 
I liked this movie, it made me laugh. Always a good thing in my books. I felt it had a bit more of a gut to it as well compared to Superbad that just seemed to trail off a bit in places.
It's well structured and sticks to what it's about.
I'd give it a 6/10
Just remember....it's a bit of nonsense!
Silly
