What makes this comic a pleasure to read is identical to what makes the show a joy to watch: they're both just pure, laid-back, semi-anarchic fun.
Teen Titans Go! (TTG) is irreverent, silly, and self-referential. It doesn't insist upon itself, nor does it try to be anything more than it is. This may sound like a backhanded compliment, but there's nothing backhanded about it. In the comic/cinematic/television landscape of mostly serious-borderline-dark superhero franchises, it's refreshing to be able to sit down and read something fun that isn't trying to fun and edgy. To make a Marvel comparison, this comic is more Squirrel Girl and less Deadpool.
Who wants to see just how involved a game of Go Fish can be? How about what a teenage superhero slumber party is really like? What happens when a series of prank calls almost ends in alien invasion? How do you feel about constantly taking the mickey out of Robin, the Boy Wonder? This comic features the heroes we know and love from the show continue being footloose and fancy-free while focusing on what they do on their off-days, when not catchin' villians.
With decades-upon-decades of canon to draw inspiration from (and parody), this first volume of the new TTG comic line is well-worth reading. It's full of great gags, humorous stories, quotable one-liners, and truly unexpected references (Oscar Wilde and Hammacher Schlemmer are two). If any of that sounds fun, then this comic is for you.
