Green Lanterns Rebirth: This book is good. I would suggest it. There is less space travel and fights. But a lot of the fights are emotional struggles. I am personally not a big Green Lantern guy but I found this enjoyable. Especially the anxiety aspect. 9/10
Flash Rebirth: I love the Flash. This book had a slow start but when it picked up, it went amazing. At times, there are gaps and holes in the plot that are not explained. But the art is stunning and the build up is amazing. 8/10.
Nightwing Rebirth: I am a huge geek on Nightwing as I found this book amazing. The writing was amazing. The artwork was astounding. It builds up to a high point and you know you are not coming down. Especially with the Court Of Owls.10/10
Aquaman Rebirth: I used to not be into the character, but this story got me back into Aquaman. The bridge between America and Atlantis is an interesting plot point. The Artwork shows every last detail. 10/10.
I was going to do more, but this is the basics. I would suggest these. More will come next month, and I will be prepared.
Maybe some DC reviews will help you make your decision. Here is Luke Goldscar's opinions on the DC Rebirth.
