I understand that "The Climax" isn't necessarily a well received" movie among Boris Karloff fans. The plot isn't much, i'll admit that, and some of the musical number "particularly the one in which Jane Farrar was the prima donna) were quite painful. But Susanna Foster's voice saves the day. This movies is no "Phantom of the Opera", but it was fun to watch. The Technicolor was magnificent, and the set design was gorgeous. Turhan Bey was an alright leading man for Foster. But he didn't seem "strong" enough, I suppose. Boris Karloff is fantastic as a menacing figure, hovering over Foster in an aura of mystery and horror. The film isn't scary enough to be considered a horror film, but too ominous to be considered a musical. There isn't a real genre for it. But it's enjoyable to watch and I liked it. I'm a big Susanna Foster fan, so it was joy to hear her sing, and I'm becoming a Boris Karloff fan, after seeing "Frankenstein" and "The Climax".
So, all in all, "The Climax" is good enough, but it could be better.
