I agree 100% that Anakin in the cartoon series is not remotely the character in the PT. But Anakin in the cartoon series is not remotely the character in the CT either...
What's the CT?
I thought the little kid Anakin in Ep I was heroic and sympathetic.
He was likable but I don't think of a child as being capable of heroism. A child that age isn't mature enough to really understand issues of life and death, and that it's not all just a fun game. I could never get over feeling horrified that the grownups would allow the poor kid to put his life on the line like that, who was far too young to make a decision like going into combat, and it made it impossible for me to take anything in that movie seriously. That movie was just wish fulfillment for the ten year olds in the audience.
I also have some iffy feelings about
Clone Wars' depicting Ashoka - who looks like she's about 12 to 14 years old - as a warrior. I can't help thinking of the real life children that age who are being kidnapped and forced to fight in various war zones around the world. The Jedi are really really creepy sometimes.
Successful or not, the depiction of Anakin in the Eps II & III was intended to show how the good little kid in Ep 1 could become the evil Jedicidal villain he was in the CT. Anakin IS Vader! How likable, heroic and sympathetic do you expect a young Vader to be?
I expect him to be likable, heroic and sympathetic enough that he deserves to have a story told about him, that I'd be willing to watch. I don't want to waste my time watching the sad tale of a pathetic, whiny, brainless punk. The first thing any character in any story needs to do is convince me to spend my time on his story.
Clone Wars Anakin has done that; PT Anakin didn't even come close.
After that, this particular character has an even tougher job: he has to convince me that his fall to the dark side is believable. Starting out with a character who's worth telling a story about to begin with, that character arc would be tricky for any writer to pull off. A five-year-long series should be able to do it; even a three-movie series could do it, if they really move quickly and don't waste time on anything extraneous. I think they'd need to start with the character as an adult, to make the best use of the short amount of available screen time. Falling to the dark side is basically a story of morality, and ten year old Anakin is too young to make moral choices, so there's little value in starting the story with him.
Anakin's fall to the dark side should also be a progression - we see how he started out as a great guy and understand what happened to him. The way the PT did things, you had a nice little kid who was thrust weirdly into adult roles (warfare and even, ickily enough, hints of romance with Padme) but came through it pretty well. Fast forward a few years, and now the nice kid is a surly, unlikable punk who falls to the dark side through sheer stupidity, or perhaps because he was so damaged by his childhood that he really never had any other choice.
The first way, the story is idiotic; the second way, it would make an okay story for a different movie, but lacks the mythic power that
Star Wars should have. For the story to have mythic power, Anakin has to consciously and deliberately make the decision to embrace evil, without being stupid, or manipuated, or because he loves Padme too much, or any such excuses. A mythic hero - or villain - must be in charge of his own story. Anakin was just dragged around by his story like a broken puppet on a string. I sure hope
Clone Wars does better.
Since there are "a lot", could anyone please post a list of the specific problems of the PT and the corresponding specific solutions that the CW provides?
A few of them are:
-Anakin is not a disgusting punk but rather is quite watchable and fun.
-Now that Anakin is not a disgusting punk, Obi-Wan and Padme no longer look stupid for being his lover and friend respectively. So all three of the major characters are now improved, and that counts for a lot.
-
Clone Wars feels more like
Star Wars than the PT does, largely because of more attention to humor and colorful, zany characters (who are fun and not annoying in that horrible Jar-Jar way).
-Obi-Wan seems to be more on-target in
Clone Wars. There was something off-putting about the PT Obi-Wan, not sure what. Maybe Ewen McGregor not looking anything like Alec Guiness was a problem? He also seemed to be a nagging wet blanket and lacked the impish charm that Guiness brought to the role.
-The stories are better composed than the PT and zip right along in an exciting way. In
Clone Wars, you have gripping war stories interspersed with a few tales of conspiracy and deceit, compared with plodding, bloated saga built around taxes and trade routes, where half the scenes are about spaceships arriving and taking off.
If you would like to not derail this thread further with more discussion of Star Wars, please feel free to PM me the lists!
I like derailing threads.

And apparently nobody has anything to add about
Star Trek and where it should go next.
