Sinnoh was the height and almost the end of my pokemon days, but I have many pokemon from it that I love. This was probably due to the fact that Sinnoh Saga lasted so long... I think it lasted for like 5 years.
Similar to my other post about Alolan Pokemon, I will do this here as well.

Honestly, I loved most of the pokemon in Sinnoh. If they aren't listed, then they just aren't as memorable or I didn't start liking them till later on. However, there are a few that I just can't stand.
Magmortar - I have never liked any of the designs in Magmar's line. Magmortar just took the ugliness and made it worse.
Spiritomb - I was never a fan of the design and I could never figure out how to catch the pokemon.
Bronzong line - Again... this pokemon was pure uglyness to me. I like Purugly more, and that isn't a good thing... At least the point of Purugly being ugly was justified in the name
Cherrim - Ok. I love Cherrim, but the design in the game annoys me. It looks amazing when Sunny Day is active, but that's the problem and I really think it is an extremely dumb problem. More than half the time, Cherrim is in its Overcast form which doesn't even look like a pokemon. I don't understand why Sunny Day must be active in order for it to be in its true form and that has always annoyed me. Cherrim's Sunny Day form should always be active as long as it is day time and not raining or snowing.
