When this show debuted in 2001, I was instantly drawn to it. The very concept was enough to get me to watch, and the humor kept me there. The adventures of Timmy, Cosmo, and Wanda were some of my favorites for a long time.
While simple, the characters were developed in the earlier seasons. Cosmo and Wanda ran away from home to get married, giving their relationship some serious "awww" factor, while Timmy was a boy smarter than many around him. I was especially pleased with "The Boy Who Would Be Queen", because it looked like they were actually going to make an interesting version of
The Libby. Indeed, there were hints of
Hidden Depths for her throughout the first three seasons.
The villains were entertaining as well. Crocker was both funny while being a threat to Timmy, and Mark made for an entertaining character. All in all, it was a great (and hilarious) series.
Then season four came along, and with it,
Seasonal Rot. Nearly every character was either
Flanderized or had
Character Exaggeration. Timmy and Cosmo became
Jerkass characters who latched onto the
Idiot Ball, both of Timmy's love interests (Trixie and Tootie) became unlikeable, and some of the worst episodes in the series run were released ("Just the Two of Us," "Timmy's 2D House of Horror," (these two for making above love intrests unlikeable) "It's a Wishful Life" (for its
Wall Banger of a
Broken Aesop)). Plus two episodes ("Shelf Life" and "Channel Chasers") pretty much use the same basic plot with different motifs and levels of seriousness. But still, some gems were still in there, like Mark's
Heel Face Turn, the
Musical Episode, and
Norm's introduction.
When
season six started, it was
Growing The Beard for me.
Poof was born, much of the Flanderization was reversed, and, on the whole, the series got good again. The "Wishology" special (which, if you watch it again, the sixth season had episodes specifically setting things up for it) gets special mention, it would have been a great
Grand Finale if not for another season.
All in all, it's a great series, if you avoid most of seasons four and five.
