Eh, we all know what's going to happen. We'll whine about the evolutions for a while, and then we'll actually use the Pokemon and get used to them all.
Tbh, they're not THAT bad. Final evolutions always have this awkward look about them when they're trying to be badass when they evolved from cute little animals. But I don't think any of them are as bad as Emboar or Torterra. So I think they're OK.
...I shouldn't be spoiling myself, but I'm using the excuse that I knew the final evolutions for Gen 5 when it came out.
