The first film is great and a veil should be drawn over the very disappointing '3' (when will studios learn that if they want to effectively 'milk' a franchise, they shouldn't skimp on the story and script?!). Whilst there aren't as many laughs in this one c.f. The first - though it still has some great jokes, it's a thing of artistic beauty! Examples include the vapour-trails on Crane's wing-tips during the defence of the Musicians' Village, and the absolutely stunning scene in the foundry where Shen is only seen as a shadow in the smoke and light from the flames. I re-watch this again and again! :o)
