Yea I thought EP 3 the light sabers were horrible. A lot of times they were improperly screened and they used some type of ILM proprietary software and they keyed the tips to look exactly the same for every shot. Looked too cartoonish.
This was way back before Mocha and AE hit the markets. Actually out of all the prequels EP 1 light sabers looked the best in my opinion because they used old fashion roto-scoping/..
Star Wars Rebels has me worried of how JJ A., is going to animate the classic light sabers. (not the new dark lord cross blade). I personally think they should not be as skinny and thin as they are now in Rebels.
As far as adywan opion of mine being too pointy, I think he only looked at the stills, and not the actual cutup.
