This episode was good, but it should have ended as a one parter, or just lost the terrorism / animal reserve aspect and kept to Batman and Catwoman toying with each other on jewel heists. The Redclaw part of the episode was okay, but it should have been saved for a later time when Batman and Catwoman had already met on different terms.
The animation was great, especially the quick running used a lot at the beginning in the Batman / Catwoman chase scene, and the falling animation used at the end of the episode. There was also some humorous moments, and some nicely done music (Catwoman's theme, Batman's theme when catching Catwoman from falling).
Overall, this wasn't the most amazing of all episodes, but it wasn't bad.
A well done conclusion to this two-parter with Batman and Robin finally teaming with Batgirl. Her involvement was not really needed, but it was a great introduction to the character. Most feel that three heroes is way too much, but the dialogue and situations with the three made it better than just Batman and Robin alone.
The animation was a notch better than last episode, but still not the greatest. There are some nice shots of Robin watching Mason, Batgirl appearing behind a subway, and Two-Face threatening Mason. They were well shaded, but this still won't make up for Batgirl / Barbara's miss-proportions.
In this episode, Two-Face was made out to be more of a gangster, which was great to see especially with the small portion of gangster fighting music during the subway station Tommy-gun fight. The music also paid small homage to the 1960's theme when Batman starts up the subway car which was nice to hear.
