Sorry to hear you think Big Fish is bland Hollywood product, I thought it was Burton's best film in almost two decades. Concurrently I was rather disappointed with Sleepy Hollow. As for this film, which is the one in question I enjoyed it quite a bit. It is an improvement over Willy Wonka and the Chocolate Factory, although I seriously doubt this one will ever achieve the cult status of the original. Can't say Depp makes a better Wonka, I wasn't overly impressed with him in this picture, but there was something particularly creepy about Wilder.
I loved the score, the songs reminded me of Ellfman's Oingo Boingo days, and I couldn't help thinking of his first movie musical score for brother Richard's Forbidden Zone. I think the children were really well cast here, and you enjoyed them at the same time you were revolted by them. Occasionally annoying characters can get too damn annoying, and I'm extremely hostile towards child actors in general so good work there. The backstory with Wonka's father was something of a welcome addition, but I really think it was just an excuse to use Christopher Lee, and you probably won't ever hear me say a bad word about him. Overall a rather well made picture, due to its nature I can't really call it a masterpiece, being both an overbudgeted CGI spectacle and a remake, but certainly enjoyable. I think it helped that Burton disliked the original film, he gave it enough of his own voice without even remotely trying to mimmick the first. And Charlie's house was pure Burton, he'll never fully shake his Expressionist roots.
