I actually agree. As "simple" as Rescue Bots is, it is quite enjoyable to watch AND Optimus has a sense of HUMOUR and humanity to him much more reminiscent of G1 Prime.
My kids despite technically being too old for the show always stop to watch it, or in my sons case sit down and watch a whole set of episodes and I always hear them laughing at it. They LOVED the Season where Optimus turned into a T-Rex and went all primal.
Back to RID, I actually think bringing Optimus back so soon was a bad idea. I love hearing Peter Cullen's OP voice and there is no doubt he draws viewers but they could have taken an alternate track and mixed it up with Ironhide... (personally I'd love to see if they could a) convince the studio to introduce Ironhide and b) convince Peter Cullen to reprise his voice).
