God help us all.
One thing that is immediately obvious is the fact that The Clone Wars is very kid-oriented. Instead of the dramatic Star Wars logo and the opening crawl sequence, the film begins with the Clone Wars logo, and has no crawl. Instead, what would have been the text of the crawl is actually the spoken dialogue of a narrator. It sounds somewhat like the narrator of the old WWII propaganda movies, and works on some level. However, I honestly hate the fact that Lucasfilm feels the need to talk down to me. I could have read the opening crawls just fine when I was four years old, and I don't need it to be read to me now. Just let me read it for myself and let my imagination do the work.
This "movie" does not have spectacular animation by film standards. In fact, visually, it's rather sub-par compared to virtually any other CG animated movie in theaters. However, for a TV series, it will be easily one of the most visually stunning shows on TV, if not the most. To quote IGN.com, the characters are rendered with a style reminiscent of "hand-painted maquettes". It's a very interesting style, though in motion much of it seems strange. George Lucas apparently told the animators to make the motions of the characters stiffer and more exaggerated, rather than smooth and lifelike. This is an interesting move, though it doesn't always pay off. Many of the character movements just look awkward or illogical, rather than stylistically interesting. The battle scenes are spectacular to be sure, but they lack a certain style. They don't have the sharp style and pacing of the previous animated Clone Wars series, and aren't realistic enough to be anywhere near as good as what was seen in the live-action films. What's left is something in-between that isn't as good as either, and falls short of nearly every mark.
The two main flaws of the film are the dialogue and the pacing. Throughout the film, there is no pause. The entire movie is one quick sequence after another, filled with poorly-written and acted dialogue. This may not be the fault of the voice actors, however, as the animation for the film was done at least a year ago, and the voice actors may have had to lip-sync to the animation, causing the lines to sound odd or ill-timed. Additionally, the "squeezing" of the already-made episodes into a film under two hours may have left the editors with nothing left to do but make every shot in the film as short as possible. I honestly cannot describe how fast the film moves. It's like watching a schizophrenic on caffeine (my apologies to any schizophrenics whom I just mentally compared to this film. You're much better than that).
There is no room for drama or a quiet moment. The film just keeps on running, never taking a break. This makes the action scenes seem no more exciting than the [very few] non-action scenes, and the dialogue less and less important. Rather than allowing for the dialogue to have any timing or depth, the film abruptly jams lines together, making it seem as though the movie's editors were having Mountain Dew pumped into their veins.
Please understand; I love Star Wars. I own at least three dozen Star Wars novels, not counting my many guidebooks, my favorite of which is titled Jedi vs Sith: The Essential Guide to The Force. I own at least fifteen Star Wars video games, and there are very few who dare to challenge me at Star Wars Trivial Pursuit. Heck, I even own a Master Replicas Force FX Luke Skywalker Episode IV Electronic Lightsaber. I literally do not understand how anyone could not like Star Wars; it's a completely alien concept to my mind. I love everything that makes up the universe of The Clone Wars. Despite this, I can't simply accept Clone Wars as a film. The upcoming TV series will probably succeed where the movie failed, but that's not good enough. Clone Wars is one of the most poorly-executed films that I have seen in recent memory. It's worse than Tomb Raider 2, The Mummy 3, and Mighty Morphin Power Rangers: The Movie. I feel as if George Lucas himself has tortured me for two painful hours of my life.
They didn't even ask me any questions...
Do yourself a MASSIVE favor and DO NOT SEE THIS FILM. It's not worth your time or your childrens'. Instead of paying for a movie ticket, go buy an action figure from the movie; you'll have more fun with that.
