Rowan felt like he just didn't give a shit.
Oak was cool and has that nostalgia value going for him
Elm was ok but overall forgettable
Birch was pretty shitty because what the fuck kind of professor needs the help of some shitty kid
Rowan overall felt very useless to anything. Here's a pokemon now get out nigger and then showing up a few times after shit happens
Juniper was ok, felt like she mattered more to the overall plot
Sycamore has been pretty good about actually mattering, but it feels like he's pretty lazy. Like, continuously calling you to come do or get something from you.
