Starting Season 15, Kari, Tory, and Grant are no longer with the show. Their salaries have apparently gone to the film production staff. There are now a lot of visual effects and cutesy sketches, a departure from the sort of "garage show" feel back when they started out in the first seasons. All in all, the new approach is a lot better than I would have expected. However, it suffers from cutting back and forth between one project done by Adam and Jamie and another project done by Adam and Jamie. I understand that they are catering to the limited attention spans of their audience, but it was less jarring to cut back and forth between two different crews: Adam/Jamie and Kari/Tory/Grant. I think the change is for the worse, but the show is still watchable.

You can find Grant Imahara on Star Trek Continues.
