RocknRolla is a fun movie. I guess the plot is sort of original, but it mainly gets by on the likeability of the characters.
I guess I can officially say I like Guy Ritchie's stuff. The Man from U.N.C.L.E was great, and I liked Sherlock Holmes and Snatch (although I no longer remember the latter). RocknRolla really pulls you in. It's engaging right from the start, and the characters are all likeable. It's interesting how little Mumbles and One Two want to hurt people, considering their line of work.
