I like all Pokémon generally. Sure, some look bland compared to others, but I think that even that makes things more interesting.
What I like about Pokémon is that there is a lot of diversity between all creatures. It's the fact that you have Pokémon based on everything from animals, to fantastic/mythological creatures, to objects and from to absolutely adorable to sheer badasses that makes it unique because there's Pokémon for all tastes.
There's always Pokémon you will like less than others, but there are also those you will like. Such tastes differ from person to person and I think it's stupid to even argue about such matters: it's somewhat against the spirit of the series. Just stick to the Pokémon you like and don't whine about others having different tastes than you, for it's a very childish behavior.
This was completely off-topic, but I had to say it.
