Recommending books is often like recommending movies...even when you have the same interests as someone else, you can still have different taste.
My husband and I rented several movies enthusiastically recommend by various friends we like- only to find said movies completely tedious or stupid. We totally couldn't figure out what redeeming features they saw in them! Still can't figure it out...and these are people we like and hang out with!
We've since stopped watching movies recommended by others except for a couple of particular people who we have found have very similar taste to ours.
