The slow pace of Shiki 2 is a change of pace for the series. It was intentional, to draw people into the scoring system. You are given time to focus on how to maximize score for each wave of enemies without worrying about survival. Basically levels 1-3 or so play like a puzzler. Survival gets a bit more hairy on levels 4-5, at least for me.
Detatchedness of the backgrounds? That's mostly true in the first two levels, but that changes dramatically after that. I'm afraid you're misremembering. Go back and play 3-1, for example.
Less good music? The music in Level 2 is some of my favorite in any game. I'm afraid your remark here betrays very poor taste.
