I really enjoyed this one, but I know what you mean about misjudging a game. I played the demo of "Hidden Expedition: Smithsonian Castle" CE and it just didn't grab me, so I passed. When the SE was released, I had a coupon that was about to expire so I picked it up. Much to my surprise, I loved it and was wishing I had bought the CE. Of course, there were also several occasions when I tried a game I hated a second time, and I still hated it
The "Midnight Mysteries" bonus game is extremely short (it took me about 3/4 hour) so, if you have a coupon, I'd recommend giving it a second chance.
