In movies: Bedazzled (the original, with Peter Cook and Dudley Moore) can always make me laugh, and The Wrath of Khan can always make me cry.
In television: The Middleman-- late, lamented, and wonderful-- is the only show on TV that has never broken my heart. And I'll argue all day that the Doctor is all one person and it's pointless to have a favorite, but Two and Jamie and Zoe have a place in my heart that none of the others can quite touch.
In music: I will listen to anything that shows off technical virtuosity, from Bach to bluegrass. But Brahms, Dvorak, and Sibelius never fail to touch me.
In food: I will try almost everything, though when it comes to animals I do prefer to eat within my own phylum. (I make an exception for softshell crab.)
...really, as long as I have those I could give up an awful lot.
More generally-- you should message me, rather than rating me a favorite and hoping I'll check out your profile, because when I'm busy, I tend to delete those 'So-and-so has chosen you' messages unread. But if you take the trouble to say something, I'll read it.
