RoJoHen and anyone else who used to watch PR but gave up: I strongly encourage you guys to watch one of the following seasons:
Power Rangers in Space (although it would help if you were at least partially familiar with the second half of Power Rangers Turbo)
Power Rangers Lost Galaxy
Power Rangers Time Force
Power Rangers RPM
All four seasons are are almost universally praised amongst the PR fandom at large, and feature a much more 'adult' tone.
