Typically, Dr. Smoov's videos contain foul language, which doesn't bother me one bit, seeing as I've posted every video I could find in the past. Is the missing cuss-words what made it not so great for you? I thought it was pretty funny and child & parent friendly. Maybe the whole thing was scripted by someone else.... I dunno
I think it was a little too cute (for lack of a better word) compared to Dr. Smoov's other work. I'll go ahead and say cuss words are what make Smoov videos funny to me, he's pretty good with background music and editing and voicework and all those other little things that usually make those comedy-dub videos unfunny to me. It sounds pathetic, but I laugh because it's like all my favorite robots are swearing.
My favorite Smoov line, delivered by Wheeljack: "Why don'cha tell him which part ya worked on Ratchet?? Why don'cha tell him how you put da finishin' touches on da f'n brain, how 'bout that Optimus, he built the f'n brain!"
