A story of how the paths of two boys have crossed as the result of a strange pink elephant. Each boy attempts to overcome depression and find love and happiness in life, through others, or even each other. All while looking back and reflecting, "could it have been different?", "could it have been better?", "what if...?" Memories fade and the past is blurred.
well... it's the same characters and it picks up about where hindsight ended. but it's going to be told in a different manner I guess.
I would say going back to read the old comic would be only if you want some character development. I'm going to get summaries and charater bios up on the web page very soon, so you could just read that. the choice is really up to you.
or you could ask some of the other people who read it.
As a fan of Hindsight I would suggest reading the archive. But that is just because I think it's a good comic worth reading through. I don't know how much applies to the new comic but it's still worth a read.
