Most Dull Generation Pokedex

[Ben 10]

From the 5 Generations that have past which Regional Pokemon from a Generation bore you the most?

 

[Life]

Johto for me. Even though I like 249 Pokemon out of the 251, their designs were quite lackluster.

 

[Pokémon Master Ash]

Sinnoh. My thumb hated scrolling through that dex when playing Pokemon Diamond on my DS, whereas Hoenn's was fast and easy to go through. Additionally, that was really the first generation where I disliked many of the designs of the Pokemon. We had great Pokemon designs like Buizel, but then crap like Purugly. xD.

 

[Rainbow]

Sinnoh. I have no problem with introducing lots of evos, but I found almost all of the Sinnoh one ugly. (Lickilicky, Magmortar, Rhyperior, blech)
