Which season did you like Team Rocket in?
Sadly, I only watched the Kanto and Johto arcs, so I can't answer very truthfully. ;; For the most part, I left Pokemon behind in middle school, which was when the Hoenn (and I think Sinnoh) arcs began for me. Of course, now that I'm in college, everyone and their mother seems to be into Pokemon. o_O
Anyway, I liked them best in Johto. The Kanto seasons were meant to establish the characters and what little plot the anime follows, so they couldn't be very creative with Team Rocket's antics.
