I actually think BW1 had a better story, but when it came to side/post game content, it was lacking a bit. On the other hand, while the story was a bit weaker, BW2's side and post game content, and maybe even the in-game content is overwhelmingly good.
If BW was planned as a trilogy...I'd be game for it. No issues. Don't know where Team Plasma or even N goes from here, though.
