Yeah - I was involved in helping a large company purchase one of these tools and it was a nightmare. The software was poorly made, and of course every corporation does things differently.
Part of the problem is that legal teams don't understand how this software works, and the companies that create it use salespeople who will promise all kinds of things, so you end up in the situation where an in-house team has been told it will cut down their hours by X%, the software isn't designed for whatever task it has been sold for, and it becomes a hack job to make it do so.
The areas like family law (or particularly executries) are great for document generators. Similarly in corporate where there is a lot more routine work. These have already come into law firms in a big way but it's not particularly innovative (though still welcome).
