Season one was kind of a slow burn, and I didn't like all aspects of it. But overall it was great.
Season Two has BEEN absolutely amazing! The Dynamic between Dick Grayson & Jason Todd is the best. Brenton & Curran do such a fabulous job with bringing these two characters to life. I love the addition of an older Bruce Wayne, and I hope to see more of Iain Glen, as the dark knight detective.
The storytelling and pace is great, Deathstroke is such a solid choice for a villain and Esai Morales is absolutely brilliant. He is my favorite live action version of Slade Wilson to date.
The one thing that might hurt the show is the amount of characters. They seem to have too many and all of them are so great and I only wish they all got equal screen time to be able to tell their stories. Beast Boy & Raven feel like weak supporting characters, and they really should be featured a lot more. Perhaps a spin off show with some of the other characters would be a great idea. Maybe we could see a Titans East show lol :)
But overall, this is the BEST superhero tv show going today. DC has a true winner with Titans.
