What a major disappointment compared to Volume 3 which I truly enjoyed. This? Not so much.

Honestly, this is like Saturday morning cartoon episodes here. Just a bunch of unrelated stories all pushed into one book. Batgirl dealing with Penguin on Christmas, fighting a blob creature that attacks woman in bathrooms, it's just really boring stories all put together. It's not awful, nothing offensive, and the art solid, but if you skipped this you wouldn't be missing much. A 2 out of 5.
