Brewdog - Beer 21

Brewdog Pumpkin King 5.5%

I've always been intrigued by American brewery's putting pumpkin into beer and wondered what they taste like. In the Uk brewer's tend not use it in beer, and then you come to brewdog who like to change things up a bit. On the bottle it says "breathe in pungent and heady mix of spicy caramel aromas, and brace yourself for inevitable onslaught of drowsy unctuous gloop that will surely follow..." It slightly worries me that brewdog have used the word gloop in describing the beer.

I guess when bought it I thought this would be more like the Rye beers that I keep trying, but it's not. I can not pick up on the spicy caramel just a not a very nice flavour or a beer.
