I know some will and I mean no offence by this, but I think people need to stop judging the starters based on there middle evolutions. It is extremely rare that the middle evolution looks better than the finals. At least that is how it is for me.
The only pokemon, to me, who have ever had better middle stages than finals are Frogider and Grovyle.
I actually really like Dartrix now that I look at it more. It still looks like an owl, the only thing is the hair. But all of that will go away if the concept arts are indeed true. And it is still possible for Split Evos. And if not Split evos, then we still have the secrete that each of the starters have.
