I hate to accuse anyone in the arts of "not caring" but it certainly feels like he's been mailing it in for a while. Here are the paragraphs about him and not the movie, although the whole piece is good.

"This may come as a shock to younger readers, but there was a time when the promise of a new Tim Burton movie was greeted, by critics and audiences alike, with excitement and feverish anticipation instead of eye-rolling and dread. I should know. As a child, Burton was one of my favorite filmmakers, if not my favorite.

...

Speaking of which, Burton would release The Nightmare Before Christmas — which he produced but didn’t direct — the very next year; for all its morbid charms, it marks the beginning of the filmmaker’s long, slow descent into fruitless self-parody. He’s done good work since then: Ed Wood is a masterpiece, Mars Attacks is a snarky, subversive delight, and I like Big Fish and Sweeney Todd more than most. But when a project looks Tim Burtony these days I almost invariably see it as a negative, particularly if Burton is actually involved."
