What about them didn't you find boring, and what about the new games bored you?
It was just that everything was quick. Combat lasted like 5 seconds. In newer games it is like they stretched everything.
That's been a problem since Gen 4. Even with animations on, Gen 2 (which was slow, admittedly) and Gen 3(which was faster and probably the fastest the series has been) wasn't as slow as 4 on has been.
Really, what drags the series for me is the fact they let you "cross-gen" your Pokemon, but they don't even bother to "check to see if you've beaten the gyms before" and give you the new gym badges as "well, here. Go grind and collect"/breaking the single-player.
There's only so many times I can run the line and get badges before I get burned out/bored of it.
