A deranged prison warden, a snarky Boy Wonder and Paul Dini's humor - 'Lock-Up' was a better episode than I'd remembered from seeing it twenty-odd years ago, and it's a good character study for Batman on his own vigilantism. "Where is the line drawn?" is always a pertinent question when it comes to cape and cowl work.
For such a one-off villain, they sure did make Lock-Up memorable. It's hard not to think of Bane when batman's facing his over-muscled opponent (as well as the third act taking place on a ship) but this is one fight that's actually pretty good. Plus, there's a brawl stop a sinking freighter. It's not a bad fight scene. Throw in some very nice animation, and it' a winner.
