The Kimi Era (2001-2004) Is The ONLY WATCHABLE Era Of Rugrats.
I can't watch any of the old episodes from 1991-2000 and the only they have going for them is nostalgia and THAT'S IT. The episodes that came out before Kimi joined the show are so incredibly dated and childish, you have to be seriously blinded by nostalgia to think pre-Kimi Rugrats is a good show.
Even Nickelodeon's Doug holds up MUCH BETTER to adult eyes than the original Rugrats episodes. And the 1997-2000 Era was EVEN WORSE Than The 1991-1994.
Also, All Grown Up Was A GREAT spin-off and got WAY TOO MUCH HATE for being...you know.. actually good.
