As a local, I think Dollywood is a very nice park. It is themed and that is the part I like. I like themeing. However, as someone who has been touched by the magic of Disney, it isn't to be compared to WDW/DL. I think if you just enjoy WDW then you just enjoy Dollywood also and not be the least bit disappointed (comparing to WDW). They are 2 different places and really shouldn't be compared. Of course, in my head I always compare but I keep my mouth shut except for "fastpass". In the summer when it is crowded, Dollywood needs FP.
I think Dollywood is a good value for the $$. It is a lot of family fun with some really nice attractions. I think you just have to be open minded.
