The only real problem with The Clone Wars, to me, is that they try to do a lot of this fanservice. The problem with that being we are generally a group of fans that don't really want it.
They should really be trying out new and exciting and different things, rather than shoehorning a bunch of old characters and concepts in, whether it works or not, or whether it can be retconned to work or not.
Oh well. At least their Chewie looks right.
