This is the second year for Central Coast Comic Con (C4) in Ventura, and as an attendee I consider it a success. There were lots of vendors, a significant and well publicized set of panels, games of all types, a reasonable attendance of celebrities, several scheduled events, and a lot of cosplay - all of it taking place over two and a half days.
Last year was pretty disappointing for a lot of reasons, and so I'm really glad the organizers learned from all of that and came back with a much stronger second year. We need a local convention, and now I have no qualms about recommending this one. Everyone I know who attended this year had a great time (although I did hear a few grumbles from vendors).
I went all three days and enjoyed each day for different reasons. I think my favorite was Saturday when I served as a guide/chaperon for a group of teens attending their first comic convention. This group had heard me talk about San Diego Comic-Con and they all wanted to go some time. I try to redirect that kind of interest towards starting with smaller conventions, that way they can get some experience and decide whether they even like going to conventions. When I mentioned that C4 was coming up, one of the fathers suggested we make it a group outing, and so we drove down on a Saturday morning with two cars, four teens (two girls and two boys), two fathers, and me.
