I'm not saying you CAN'T like it. I'm just saying that it is a very kiddie game, obviously intended for children. I know some people, especially those with Peter Pan syndrome, actually like the game. But can we admit that it's a children's game and is very kiddie? Look at the evidence:
1. Targeted toward children (especially evident from the anime)
2. Extremely easy and child friendly...no real challenge
3. Very simple battle system...no real effort put into it (kids won't notice that)
4. Only real appeal is a collection factor which always sucks kids in
5. Cute little animals
6. Childish dialogue
7. Children's lessons to be learned in the anime.
