I like them well enough. I think a lot of people dislike them for their designs and because they have medium-low base stat totals. They aren't terrible though, even if they aren't super amazing. The frustrating part is that they have stone evolutions, so you have to keep them unevolved until about level 30 at least or they will suffer without the right TMs. But compare Simipour to Golduck. The BST is actually very close, but Simipour is slightly more offensive and less defensive. The main difference is the lack of an evolved level-up moveset and good ability. The monkeys all have gluttony or torrent/blaze/overgrow, which are usually not too helpful. So that really means they rely on their designs to be well liked, like Golduck does if we use the same comparison. But unfortunately, a lot of people just think they look ugly or silly. Not me, but I see that take a lot. I do think Simisear's pose is super goofy though.
>>56457321Anon is saying it was a poor attempt at giving the player a second grass/water/fire starter pokemon, similar to the Kanto starters received from Professor Sycamore in the next gen.
