I think the Therian forms are a big improvement over the originals, mainly because the originals were a bit too pallette-swapish (even though each one did have other details that were changed beyond just color). Though I don't hate the original forms or anything, they were alright, but not amazing. I still like the new forms better, they have more individuality, and even putting aside the similar appearence of the original forms I still like the new forms better just on looks of each alone. Especially Landorous' therian form, who not only looks much better but is probably one of my favorite legendaries ever appearence-wise.
Tornadous' new form is my least favorite of the 3, though. Its a bit too standard. Its a bird, nothing really interesting or unique about it. Though it is the best looking shiny of the 3, so I guess thats something.
