If you're missing the high-level intensity that the previous Spider-books are famous for, I HIGHLY recommend looking at the recent issues of Amazing Spider-Girl. Recent issues have really brought up some disturbing/intriguing questions about what will happen next. Also, it's shaping up to be a quite disturbing Green Goblin-related arc.
If you don't believe me, read ASG #19-24 and the upcoming #25. You can also read #19-#24 in one shot in the upcoming ASG Vol. 4 trade.
