The first season was much better, no question, but the second season is still awesome if I focus on the "Veronica is an awesome detective" aspects.

Weevil gets Veronica. He's always been willing to step forward and kick ass on her behalf. And more importaintly, she's always trusted him. She's been more inclined to see him as innocent until proven guilty, whereas she's inherently suspicious of anyone else she knows until she's dug up enough to know they're innocent.
