I think once everything went into parody mode (which was done at the end of the series), the Chipmunks managed to find a weird, interesting niche for themselves. Otherwise, the early seasons were by-the-numbers fare and not remarkable, per se. Although, even the worst was still watchable compared to today's standards (or lack thereof).

I want to say watching this was my old shame, and yet, the parody stuff does amuse me. So, call it a draw.
