Someone else who understands cinema.
The prequel is considered an equally great movie.
The sequel has Karloff, Lugosi as Ygor , Rathbone, and Lionel Atwill as the one armed police inspector ( made famous again in Young Frankenstein as was Ygor)
But like you, I think the Bride of Frankenstein was the pinnacle of cinema in the series.
Although not as great as the original, I enjoyed Rocky II. Also liked Back To The Future III.
Every horror film directed by James Whale is a masterpiece. I love The Old Dark House as well. Ernest Thesiger is both hilarious and creepy as Horace Femm.
