I'm a bit of a history buff, and love to see history kinda sorta come alive. Of course, the powers that be often take considerable poetic license, but I'm usually okay with that unless something is just too ridiculously inaccurate or not consistent with that particular period of time. Well, except for Mel Brooks movies, when I can overlook just about anything.
Also, I love the period costumes, and have been known to watch really awful movies just so I can drool over the pretty clothes.
I love all kinds of movies, except horror. I also don't like movies with a lot of sex. Been there, done that, don't need to see it on the screen. I do love a good thriller. (like Rear Window)
