R2 looks like shit for almost the entirety of his screentime in that film.
R2 looks like shit for the entirety of both AotC and RotS. Heck, even the physical prop in TPM looked wonky as for some reason they decided to make his dome matte instead of glossy and reflective.
The fact R2 is even in that movie (not film) is shit.
Seriously, fuck those movies.
