I actually thought Unia was a logical progression from Reckoning Night. I understand it was a "grower" for a lot of SA fans, but I liked it immediately. Maybe it helped that I bought the 1st four SA albums around the same time, so I could hear the direction they were headed. Each album by Sonata Arctica seems to be a little bit different from the last, but also retains some of the same sound as well. It'd be pretty hard for me to pick a favorite album by them, but I like their last two albums as much as anything else they've ever done.
