Just as enjoyable as Vol 1, if not better.
Batman and Robin Vol 2: Batman vs. Robin contains Batman and Robin #7-12. Just as in Vol 1, the art is all done by Frank Quitely and is very enjoyable. This continues the story of Batman and Robin Vol 1 which raps up in Vol 3 and is my favorite instalment of the trilogy (if you want to call it that). The story has some twists and turns and the reveal at the end is totally worth it, especially since there are clues dropped along the way. As I have said in my other reviews, this is part of the Grant Morrison Arc that will be detailed below, but the Batman and Robin trilogy could be read alone outside of the other stories. This picks up from Vol 1 after the events of Batman: R.I.P. and Battle for the Cowl. Again these are my favorite B&R as the dynamic between the two is very enjoyable to read and watch and the story is engaging. Pros: -B&R are amazing -Art is solid -New characters are fantastic -Original story line -So many little clues as to what is going on -Grant Morrison Cons: -Grant Morrison -Relatively Short -Vol 3 (see review) *Morrison's Story Arc is as follows: Batman and Son (Included in Black Glove Deluxe Edition) Batman: The Black Glove Batman: RIP Batman: Batman and Time (or Final Crisis but still needs 701 and 702) Batman and Robin Volume 1-3 Batman: The Return of Bruce Wayne (Technically happens during Batman and Robin Volumes 1 and 2) Batman Incorporated (and Leviathan Strikes) Batman Incorporated Vol 1: Demon Star (New 52) Batman Incorporated Vol 2: Gotham's Most Wanted (New 52) A readers guide to Grant Morrison's Batman is a great help if you are looking at the whole series.

An Excellent Continuation For The New Dynamic Duo
I really loved Batman and Robin Volume 1. This arc is my favorite part of the Morrison Batman run, even though I really struggle with and don't enjoy everything that comes before it. But it's worth it for this duo of Dick Grayson and Damian Wayne. Volume 2 gets off to a slow start with a few issues about a deranged Batman resurrected by a Lazarus pit. Readers who haven't read Morrison's other work, including Final Crisis, will be confused by what occurs here. But the gist is that Dick and Damian learn what the readers already knew, that the corpse they thought was their father wasn't his (instead a failed clone from a Darkseid experiment), and that their father is out there somewhere. The art in these initial issues is also a bit rough and lower in quality, which is the only reason I brought this down to 4 stars. The second story in the remainder of the volume though, that pits Damian against Dick and tests Damian's loyalties is a great continuation of the Batman and Robin story and might be one of the best parts of the series. Damian may be rude and sociopathic, but this arc gets to let him shine a bit and show that he really does care about his big "brother" Dick Grayson, and about his father's legacy. As a bonus, there is a running mystery about the duo's new ally Oberon Sexton, which I thoroughly enjoyed. I won't spoil the ending, but it's a truly fun reveal that makes you rethink Sexton's role in the adventure in an interesting way. Again, this is a great story for Batman/Dick Grayson/Damian Wayne fans that I strongly recommend.

Not Perfect, But Loved It Anyway!
Format: Hardcover
The cover and title of this collection are slightly misleading, but it's still a fantastic read. Robin isn't willingly trying to kill Batman, however, I'll let you find out what's really happening yourself. I love the new Batman and Robin team of Dick Grayson and Damian Wayne. It's a fun change of pace to have a more lighthearted Batman, and a bratty and brooding Robin. This is the second collection of the new Batman and Robin series, but I still enjoyed it without having previously read all of the first volume. The Highlights: Batwoman, a zombie Batman, Talia al Guhl, Slade Wilson, the mysterious Mr. Sexton, the history of the Wayne family, and the beginning of a Joker story line. The new flying Batmobile is awesome. I love Grant Morrison's writing, and here he writes a fun and interesting Batman adventure. Things to Consider:There are two different artists in this volume. The first half is decent, and the second half is more unique with some great pen and ink work. I enjoyed the second part a lot, but it's not quite the classic super hero style art you might expect. This may not be a groundbreaking story, but this series is great. So if you're interested in Batman and Robin, you won't regret checking this out.

Wow! Great Stuff!
Format: Hardcover
Before I read this book, I had just read the other recent Batman trade, "Life After Death" by Tony S. Daniel, and I was seriously disappointed. I really struggled to get through it. So the next night, I started to read this one, Batman vs Robin, and I couldn't put it down - I almost read the whole book in one sitting (if it wasn't late at night, I probably would have finished it). It just confirms, once again, what a great writer Grant Morrison is. In this trade, you get two main story arcs (with a nice "cameo" by Batwoman in one story) and the search for Batman really starts to develop, here. I enjoyed Volume 1, but IMO, this one is far superior.

It gets AWESOME. I highly recommend this
First volume is kind of a drag, but it gives backstory and character development for this volume 2. It gets AWESOME. I highly recommend this, it has mystery, action, and great art. Fun read and you MUST read the first volume.
