I felt the same way about the pilot. For me, I liked the show to begin with, but didn't love. Around the fourth or fifth episode, things really start clicking together, though. Characters that seem one-dimensional, like Logan, the garden variety bully, start becoming very interesting. Depths start being revealed in the characters' relationships, and the flashbacks that detail Veronica's transformation to ditzy (on the outside), popular girl to weathered sleuth becomes even more interesting. So, yeah, stick with it, if you can. It gets most excellent.
