Welcome to just about every action-based cartoon show for the last sixteen years. Why people are so surprised about this is beyond me.
Is it too much to ask for development of the current characters before random pleas of new main cast dudes?
What's more to develop? Ratchet is exactly like Animated, and he hates humans. Prime is the same Prime we always have. BB is a kid. Bulkhead is a buffoon. Arcee begrudgingly accepts her role and human partner. What more do you need, they're robots!
What more should they develop? It's only 8 episodes and there has been much developed. Storywise this series seems already like the holy grail of Transformers. At least if they keep up the good work until the end and they keep on topping it.
Knowing their personality =/= development. This isn't shitty G1 where people were satisfied with catch phrases and speech problems, here we actualy learn what they are like, why they are like that and grow out of their problems.
They're machines, we don't need to give them psych exams. You're right, this is more like shitty Animated. One off characters, no episodes flowing from one to the next. The same five Autobots, the same two Decepticons, the same angry Ratchet, the same dimwitted Bulkhead, movie BB, elder statesman Prime and some kids. I can see how this is the best version of TF yet. Any bets on if Breakdown appears in more than one episode, or, better yet if he's the lone Decepticon in this new episode but still somehow manages to take on all five Autobots by himself?
