Personally I love seeing all of them in full 3D, totally awesome *3D cookies* there were some weird ones though, definitely, but in a good way...
I'd say, Spiritomb looks pretty weird, not what I expected, but cool all the same and Roselia appeared a lot smaller than it was portrayed in the anime O.O I think Hippowdon looks odd without all the sand (looked good in its episode though) and Camerupt looks a bit like my dad imo so that's a bit freaky XD
But, as I said before, they all look awesome none-the-less ^^
