I'm excited about this game. Overlord 1 was really cool, even with it's flaws.

Eurogamer also: http://www.eurogamer.net/articles/overlord-ii-review?page=2 

Played the demo and I was majorly unimpressed, it seemed lack luster and simple.

the demo was ok but not a must buy game, its more like a rental game to me.

I loved overlord 1, cannot wait for 2

It seems the demo doesn't really display all the new features they've talked about but i did like the new minion wolf mounts.  The way they're able to jump over gaps to areas normal minions can't go is pretty neat.

It sounds like they've still got the charm of the first one so whether or not you liked that one will determine if you like the new game(with all the new bells and whistles they've added).
