One show I never saw live but was still rather disappointed with based on the recording was "Woman In White." Now, if you buy the CD, it has the entire show, with all of the dialogue and everything (and the CD came with the libretto), so if you listen to it, it's like listening to a radio broadcast musical. That said, I know a lot of people have said the staging was terrible, so I apparently wasn't missing much.
Well, before I got the CD, I'd heard many of the songs-- "You Can Get Away With Anything," "I Believe My Heart," "All For Laura," "Evermore Without You," and "If I Could Only Dream This World Away" (Anne Hathaway's version). I liked those songs a lot, and I was rather disconcerted when I got the CD to discover that there were surprisingly few "songs." It was mostly recitative, and recurring themes flowing into recurring themes with very few standalone numbers.
I still like the CD, but I was expecting better based on the songs that I'd heard beforehand. (Also, I was not impressed with Michael Crawford's turn as Count Fosco on the CD, because I'd seen several videos of Michael Ball playing the role on youtube, and I thought MC seemed really miscast.)
