TPM Anakin, AotC Anakin, RotS Anakin
This is almost a thread idea, but it will work here…
Which of these is the worst Anakin?
AotC Anakin is the worst for numerous reasons that don’t need to be repeated.
TPM Anakin was annoying and a colossal waste of time but because the character slate was effectively wiped clean for the next movie, a brilliant AotC Anakin could have pulled that character round.
RotS Anakin is clearly the “least worst” of the three. Because Lucas did an “Oh f**k I’m on the last movie and I haven’t even got round to establishing Anakin as being likeable and being friends with Ben!” the opening act tries really hard to do both, while not quite succeeding. After that point, Anakin being creepy and evil works in that movies favour given the Vader descent.
