The scene where Obi-wan just takes the lightsaber and leaves Anakin on the shore is particularly stupid. It’s one of many stupid scenes of course, but it stands out as being a case of the ‘whatever just get to the Vader suit’ mentality. The whole thing is written this way.
Random story - I walked out of the theatre with my brother after seeing Tom Cruise’s War of the Worlds. His reaction was ‘well it was still better than ROTS’.
