Smurfs were always grotesque devilish garbage, and I say that having been around the early 80's original Smurfs hype. Garfield on the other hand has long been a wonderful thing, and it just got ruined with the computer/live action film, dtv cgi films, etc
To steal someone's revue of something else entirely...
The Smurfs is something that if you don't like as a kid, you'll never acquire a taste for it as an adult. But then again, I kinda think, retroactively looking at the show and the comics, that Fred Silverman and Hanna Barbera sort of ruined it... not in the destroying the concept to make a idiotic movie for dummies way... more of a making it slightly more American and kid friendly 1980's TV Broadcast Standards and Practices way. I mean, think about it this way... it took over 20 years for the US to get it, and we only got toys first. Then the show came about because the network head's daughter had the toys. Of course, there's some subtle, unexplainable Franco Belgian quality and humor (coming from someone who reads Franco Belgian comics infrequently) that's completely lost... and of course, BS&P would NEVER have let Smurfs punch each other out, like they actually do in the comics.
I kinda feel the same way about TMNT... the cartoon makes everyone think of Cowabunga and pizza and characters that weren't present in the original comics... and NO ONE realizes they were trained by Splinter to be assassins to kill Shredder.
Of course... the 1980's cartoon closest to the original comic source material that wasn't a DC or Marvel comic was... oddly enough, Ducktales... and even then, characters were added and subtracted. Smurfs actually is kinda close, even using some stories from the comics in the first season... but in a cleaned up, American, non-violent kiddy way.
