I always hated Cosmo's episodic running gags, Timmy's arrogance, the depressing negligence of his parents, and the irritating art style. I liked the show for about four seasons, then eventually said to myself "Why the hell am I watching this?" and stopped (around 2006)
I remember when this show originally premiered on Oh Yeah! Cartoons as a pilot, and I grew up with the series.
But the quality has drastically changed because...
1.They gave Cosmo and Wanda a baby, which apparently fairies do via males being pregnant instead. So thus most of the episodes tend to be centered around Poof, or Timmy having lost Poof or something... Which is strange considering older episodes when Cosmo and Wanda saw babies, they didn't care or give any knowledge/interest in having one themselves. What made them want one now? 1a. Now Timmy is getting a magical fairy dog as a pet [link] I mean.. he technically has 2 "fish" already. Wouldn't his parents be a BIT suspicious? Unless the dog is being completely hidden from them unlike Cosmo and Wanda in fish form. 1b. Overall a sign that an animated series is going downhill is when they begin to add new characters who frequently appear in future episodes (like every new episode mostly). The same happened with Nickelodeon's "Rugrats".
2. The characterization has definitely changed significantly. Like in older episodes Timmy would selflessly make wishes for his friends and even his parents because they were upset. Now in the newer episodes Timmy is portrayed as a selfish brat. Along with Mr. Crocker somewhat, because there is 1 episode where Poof becomes his "son" somehow, and he.. doesn't seem to acknowledge the crown he's wearing or anything.. what happened to being obsessed about catching a fairy? There's one in front of you!
3. This is probably more personal but, we hardly get to see any of the older characters from the show. What happened to Chester and AJ, his supposed "Best friends"? And one more thing, what about Vicky??? Considering Vicky's abusive babysitting is one of the main reasons Timmy got his fairies in the first place. Where is she?!
Might I add the now present continuity issue, because at the end of Channel Chasers where Timmy's 'future' was told with his fairies being given to his two children. There is no Poof with them, or Sparky :V Just our favorite pink and green haired couple.
There was one more flaw in the series I forgot about... Poof's anti fairy, Foop. In the canon of the series Anti fairies were basically black/blue recolors of their original fairy counterpart (some with minor edits at the most). Which Foop.. clearly isn't considering he's a cube with legs and arms. And his name.. again, the anti fairies names were ALL "Anti Cosmo, Anti Wanda, etc.." why does Poof's anti fairy get a unique name set apart from the other anti fairies? That just bothers me sooo much.
I'm glad this show is almost over. It's turned into such a bad show now and with the episode coming up on Thanksgiving weekend, I heard it's the last one and I hope so. The days of the FOP have ended and it's time to give it a burial before it's even more ruined.
