Worst deathtrap ever. Seriously. I understand it's come to be accepted fare, having the hero at your mercy only to use an elaborate deathtrap (I've always preferred on-the-fly deathtraps like in The Clock King, myself), but this was sad. Tie up two escape artists, back-to-back, leave their weapons with them, and as the obligatory slow finisher, the very thing you're using to threaten the city? Bleah.
That said, outside of The Worst Deathtrap Ever, I must agree with the sentiment that this was a weak episode. Two more things of note: First, the big escape sequence... it kind of dragged. I don't know why. It shouldn't have. But it did. And I know this isn't The Batman, but really, can we have a Catwoman-Red Claw fight that doesn't consist entirely of Red Claw kicking her?
The finale did have some semblance of a grand... thing... oh, who am I kidding. Not good. Waste of not one but two perfectly good episodes.

(Well, it was worth a go.)
