In my experience people who have trouble with ORM usually try to use it for something which it is not well suited for: namely OLAP. ORM can really get in the way when you want to express groupings, aggregates, and all kind of joins sprinkled with let's say stored procedures. But this has nothing to do with the ORM itself. It's just a fact that many people don't understand/consider the tradeoffs before jump into acting on something.
