I don't really watch too much anime other than Pokemon
Hey now, the Pokemon anime's actually a pretty enjoyable watch if you drop your preconceptions
about things like "MISTY IS BEST AND ONLY GIRL ALL THE OTHER GIRLS SUCK!", "BROCK ROCKS ALL HIS REPLACEMENTS SUCK!", "ORIGINAL SERIES FTW! NEW STUFF FTL!", "ASH SUCKS AS A TRAINER!", and so on and so forth. Did I miss any complaints?
If it helps I don't have Omega Ruby.
...You missed a lot of rational reasons for not finding it enjoyable, but I'll be nice and say you at least got all of the trollish reasons.
As for Misty and Brock, eh they're not my favorites but people have their reasons for preferring them.
