Lighthearted plot, but some heavy-hitting action.
Not perhaps what I was expecting from Besson, De Niro, and Jones, but felt it probably didn't deserve the hammering it got from Rotten Tomatoes.

This film is awesome.
An almost tantalising delve into a situation where societal norms and civility are inexorably peeled away.
I loved that things would almost reach a resolution, only for an ill-spoken word to spark continued descent into carnage.
The closing shot is possibly the most winningest shot ever, and makes the entire film.

This is my favourite Adam Sandler film. Something completely different, and yet Sandler still comes through.

A stark, bright palette of primary colours - primarily blue - complements the feel of the film very well.

I'd call this a must-watch.
