The Paldean mon are probably the group with the most experimental designs. Because of that, my first reaction to them was negative, but in 1 or 2 days most of them had already grow on me to the point my general impression of the dex is very positive.
The box legendaries are an absolute hit, the sub legendary quartet looks amazingly unique, both groups of Paradox pokémon are great, and there's so much of the regular monsters that I like. The dex has some of the most badasses serious designs in the franchise but also a lot of silly stuff (which is always important since there's nothing as boring as something/someone that takes itself too seriously).
Unfortunately the starters never grew on me. I don't actively dislike any of the lines, but I don't particularly like any of them either.
Since I barely saw any videos of Skeledirge in motion, I think there's still a chance this one might grow on me, but overall it is the only starter trio, alongside Kalos, that I don't feel excited about any of them.
