I actually like DeNiro's take in Batman Returns, you see. I think it's the strongest preformance in that movie and in the Burton/Schumacher pictures in general.
DeVITO you mean. Probably a Freudian slip on your part, given my reference to DeNiro's Capone in my post.
And I like DeVito's performance too, though I think the strongest performance in those movies was probably given by Michelle Pfeiffer, with maybe Michael Gough as a runner up. DeVito's Penguin wouldn't fit into the Nolanverse, but he was pretty perfect for a Burton movie.
