I went to the "Veronica Mars" movie starring Kristen Bell as Veronica. If you've seen the series then I don't have to list the characters. And if you haven't, then they won't mean much to you.
But you CAN go the the movie even if you haven't seen the show and still enjoy it. But if you go, make it soon. It is one of those special releases that may, or may not, be shown for a couple of weeks, depending on how many people attend.
Of course, you can buy all three three seasons of the TV series, and the movie from Amazon.com .
The movie is GREAT. And most of the old, familiar actors are back, and do a wonderful job recreating such delightful characters.
I don't know what else I can say, except if you DON'T see the movie, you are missing out on a good time!
