Very casual mystery fan. I have vol 2 of the Charlie Chan DVD set, but only because it has Charlie Chan at the Opera with Boris Karloff. They’re not bad movies, but not amongst my favorites. Even as a Karloff fan, The Mr. Wong series never did much for me.
As far as Sherlock Holmes, I’ve seen very few of the Universal series, which I need to remedy. I do own a copy of Hounds of the Baskervilles from Fox (as well as Hammer) and dig that film enough. The Thin Man series, not bad, but again, a casual fan.
But yeah mystery, as well as straight sci-fi is OK, but I’m a bigger fan of straight horror.
