Yep, I enjoy a Ratchet heavy episode as well. I liked the way they managed to convey a feeling of failure in Ratchet in regards to BB's voicebox. You can see that being unable to help really wieghs heavily on him.
The opeing scene with BB retrieving that spark extractor was awesome! I even rewound it and watched it again! That's what I like to see, Transformers using their vehicle modes seamlessly in battle, which is something we rarely see. I did question why Megatron didn't transform to chase BB though...
The MECH guys remind me of the Road Jammers and I hope to see more of them (as long as they are a proper threat). I was thinking that if they get that robot working, we could end up with a Centurion character on our hands...
The Knockout time was great! I think I love Knockout as much as Ratchet!And the ensuing chase with BB grabbing the old truck! Nice improvisation, well until it broke...
What I found really interesting was when BB tried Transforming just after having his T-cog removed. In the shot where it shows his chest about to Transform, the bumper section moves in two different ways each time (first up and then outwards IIRC).
Could this mean that the Transformers can change the 'way' they Transform? If so, this could explain the slow and fast Tfing in the movie. (which my friends always questioned; "Why does Optimus TF so slow in the base, but can go really fast in battle?).
But BB was annoying with his impulsiveness. Hopefully this will be a lesson to him and he will learn that there is more to battle than just speed and action. Now I await another Bumblebee figure that can't transform and it will be called "MECH Victim Bumblebee."
As for Ratchet in the field of battle, even though it is nice to see him, he is old and probably better suited at the base, although I can see he still manages to kick a bit of arse when required!
