Probably average.
Quite amusing in places, Kevin Hart did a good job of being the clichéd black guy who screeches a lot and surprisingly only made (I think) 4 references to race throughout - not bad for a predominantly film - of - colour!
I quite enjoyed the 80s film references - Roadhouse and Sixteen Candles (if you're black you won't have seen the latter obviously... well according to Hart - but then again by the end of this even he's not sure what is racist - "A black Will Smith" oh my!)
