Quite dull. Had heaps of potential in terms of a pro-gender-equality message and to highlight the unnecessary restrictions placed on women in society. However, this theme isn't developed very well, being fairly predictable in its progression. The main theme also gets relegated to a sideshow due to the Yentl-Avigdor-Hadass love triangle and the repercussions of Yentl posing as a man.
The story ends up being quite dull and farcical. What's worse, it's a musical, and the music is mediocre at best.
Only worth watching for the cultural references in other movies and TV shows (mainly comedies).
On the up side both of the leads were very strong. A well acted movie, but even that couldn't save it. Just like Barbara's voice couldn't save the music. Still, there were several truly enjoyable well written scenes, all in the early Yeshiva days, that I wouldn't mind seeing again.
