Yes. Around the time of the "Golden Armor" incident. That was it for me. The deus ex machinas, the constant Team Rocket interruptions, the repetitiveness, the boredom... I got tired of it all. It wasn't fun to watch anymore.
When I heard the fandub about a year later, I was glad to have made the decision I did. I still watch some episodes now and then, but really not often. I'll watch the old ones for nostalgia, but honestly, I kind of outgrew it. It just isn't fun to watch anymore, for me anyway.
