Asking what I think of fan edits is like asking what I think of people.
Some I love dearly. Others I want to crush with my fists. Some I want to love dearly while crushing with my fists.
Adywan's Star Wars Revisited is an example of a fan edit I hold close to my heart. MagnoliaFan's TPM is okay, though there is too much dialogue reading involved, which detracts from the visuals. I have the same gripe with subbed anime.
