>>51181540FRLG was the downfall. It got good again in DP, then downhill again until BW.
It's to the point there's a curse where the arc based on the initial gen releases are great but the arcs based on 3rd versions and remakes are horrible.
Also, the fact that doing RS's release schedule was so inconsistent it had the effect of making the writers always extremely behind when it comes to adaptations and is its main issue now.
