A real blast - Burton (and the cast, especially Keaton who, I suspect, would play the role for free) were clearly having a great time, with Burton taking full advantage of modern technology which, combined with all the design aesthetic and physical effects in the original, really takes things to new heights. Even then it doesn’t just feel like he’s going through the motions - there are, for example, two flashbacks in widely different styles, apparently just for the hell of it.
