I've seen their IMDb pages, and it seems that Eddie had much more work/success than Joanne post Warehouse 13, and I just wonder - How come?!

Joanne Kelly is a good TV-actress, and she should've been offered a lot more parts in different TV-shows, but apparently it's actually Eddie McClintock that get the most work post Warehouse 13, and not only that, it seems that everybody else on the show has got a lot more work than Joanne Kelly - is she such a bad actress, or is it just bad luck?
