The Tragedy of Cartoon Sequel's (A Critique)

So, today while I was eating breakfast I happened upon the "sequel" to the original Rugrats cartoon show, "All Grown Up". The first thing I noticed was the fact that throughout the entire show the characters were... Well... Out of character! Tommy who, in the original show, was the adventurous one was more cautious, laid-back, and at times embittered towards his brother, Dill.
The twins, Phil and Lil, had completely alien character traits. Phil was a kleptomaniac of sorts, and Lil seemed to have gone mute. The parents were nearly non-existent. In a strange-twist, the former baby-sitter, Susie, and the Bully, Angelica, had their own side-plot. All in all this was a major disappointment for me. The show had taken a definite turn for the worst in a desperate attempt to gain a foothold in the "tween" market.

FYI

Both the original Rugrats and All Grown Up are on Nickelodeon
at 6:30 Tues-Sun and 7:00 Tues-Sun (all PST) respectively.
