W00t! ^_^ It's cool to see which ones you guys like!
Lol I don't have anyone in real life to talk about Pokemon to, so I don't know which ones are popular among most people, but I hardly think any one Pokemon in particular could be considered "overrated." If a person likes a Pokemon, then like it! If it's a popular Pokemon, then obviously there's a reason, just like a lot of people like Pikachu, I'm assuming. Who cares if one person likes a Pokemon or if a million do!? :D It seriously does not matter. What matters is what you like!
