Everyone I've talked to who has played it have said it's awesome. If you've played the first one and enjoyed it, you'll more likely than not enjoy HR.
You'll probably want to talk to someone who's actually played it, though, to get a better idea. Sage did a livestream of it a few nights ago, you should be able to find a replay of it in his thread somewhere in the LP section. (What Sage's stream when they're bored, I think it's called)
