The CGI series is alright. Even though a couple occasions, Mark kinda reused some plot concepts from the old series... like the invasion of the lasagne creatures from outer space episode of the new series is similar to the (actually quite funnier) older episode about the invasion of the ventriloquist figures from outer space (which featured ventriloquist turned voice actor Paul Winchell). But there's something lost in translation, since the new one is actually French, and I wonder how much Mark actually writes.
It misses that very looney feel of the old series... episodes with titles like "The Creature that lived in the Refrigerator, behind the mayonnaise, next to the ketchup, and to the left of the cole slaw," plots about weird holidays where Roy smashes pies into Wade's face, and the characters complaining about the lousy parts they had in the episodes... I understand not continuing that sort of humor for something new... but some of the word play is gone. Still, I do dig the new series, from what I've seen of it.
But the old series was amazing. Garfield has always been better in animated form than comic strips. I especially love the backhanded episodes about 1980's cartoons (which did a beautiful mash up between He-Man and Transformers) and the similar, but just as wonderfully satirical stab at the then current X-Men series.
I'm lucky I got the last 2 box sets... the episodes they refused to show in syndication.
