I went to see this last night and thought it was great fun. Intriguing storyline (utter bollocks but hugely enjoyable), Downey Jr is great (as is his English accent), great support from Jude Law (always better as a sidekick than a leading man, anyway) and Mark Strong. Will say that Rachel McAdams and Kelly Reilly were underused though. Great Morricone-esque score by Hans Zimmer too. Well worth checking out.
