Looks aren't everything. But in movies, it means a lot. One of the problems that I had with the Anakin character was in the casting. I think GL made a mistake by casting a pretty boy as Anakin. I know it is subjective, but GL should have chosen an actor with an edgy look. An actor with an appearance that would have conveyed a darker vibe.Jar-Jar was never funny to me, even when I was younger, though I was 15 when TPM came out.
I also tend to agree that Anakin didn't really gain any credibility with the audience. I think, in terms of character development, Luke was far more the everyman, who grows in to the hero. Anakin is "the Chosen One" and that can separate him from sympathy with the audience. As much as I understand that Anakin's fall is tragic, there isn't a moment where I feel like he is a real person going through a real crisis. He feels fated to be Darth Vader with no redeeming quality to endear me to him.
Is it the writing? Probably. I certainly don't fault the actors, but I struggled to connect with Anakin.
Hayden Christiansen too often looked like a deer in headlights.
But of course, that would only be a part of it. The ability to act the part is vital as well. HC didn't deliver on both accounts.
In any case, the PT wasted too many scenes with fight scenes and other massive cgi scenes. I think GL got caught up with the allure and dazzle of his own cgi, when he should have devoted more of the PT to character development, specifically Anakin's development and evolution to the darkside. HC still might not have been able to successfully pull it off, but at least a more thorough attempt would have been made to achieve that end.
TPM was a complete waste of time. It almost came across as the Jar Jar Binks show. I think it might have been better had Anakin been introduced as a troubled teenager in the first movie and then proceed from there. Forget about Jake Lloyd and the kid stuff.
There was one actor whose performance was even poorer than that of either CH or JL. That was Samuel Jackson's. Jackson was wooden and his speech was very stilted. Just terrible. Jackson was the big name actor whose performance failed miserably, imo.Poor Jake Lloyd acted as well as any 9-year-old can be expected to act. GL's deficiencies as a director (he's best as a big-picture story guy) show through. This is also evident in that by RotS the performances from the stronger actors are either phoned in (Jackson, especially in his pronunciation of lines), or just off the rails (Portman). A stronger director could have fixed those two.
I think some of the seemingly odd cgi details might have been inside jokes created by the cgi artists. The odd details may have been created by the artists to amuse themselves. They were suppose to be noticed by their creators and their fellow colleagues when they viewed the movie, and not by the general movie audience.and some even suggest that he is Darth Plageus, jumping body to body (literally becoming the bigger fish that eats the smaller fish while jar jar's body is passed out.) There is a scene where his mouth is moving a little bit in the background while possibly controlling someone. They keep pointing out that as a cgi character, every tiny detail is done on purpose. They suggest that it was all supposed to parallel with Yoda, who misrepresented himself to Luke, and acted like the strange weird hermit in the woods, until revealing himself as the Jedi Master.
