I hate how much of a caricature their entire defective squad is.
You have Rambo, who is the only one I like and find half way decent in character design. Probably because he's the least altered in appearance, voice and acting from the other clones. He comes across like a less badass Arc Trooper.
Echo is good, he's a long established character in Clone Wars.
Doctor Dude is your stereotypical aloof, detached German sinister medic mixed with an engineer.
Sniper Dude should have a mustache to twirl, and he tries too damn hard to make his voice sound deeper
Retard Hulk Clone is this space marine looking guy with the mind of a five year old. Fucker literally sleeps and plays with a plushy.
