This is an interesting little bit of filmmaking.
Clearly they went to great pains to recreate Vader and the Death Star, as well as putting Alec Guinness’ likeness on a double of Obi-Wan. It’s a lot of effort.
It lacks restraint, however. It’s too over the top. It would never look right in the movie, as the few bits from the movie that are kept in this edit show. It’s just waaayyyy too much.
Still, it’s interesting to see old settings and actors recreated so convincingly.
