Consistency of Design
The design of this web site is somewhat consistent. Most of the major sections of the site have the same design and layout. However, the specific pages for the TV shows each have a custom design related to the show, and the video section also has a significantly different design that the rest of the site.
Ease of Navigation
This site is generally easy to navigate. It has a consistent navigation bar at the top that gives easy access to the major sections of the web site. One annoying navigation issue is that the logo on the navigation bar, which also serves as the link to the home page, opens a new tab in my browser instead of just returning to the home page.
