Generally very poor user interface. Episode selection/navigation while streaming is nonexistent, there is no screen lock feature, pausing on a desktop will pull up an add for other Paramount shows (so you can't pause to e.g. show someone a scene), you typically end up watching 2-3x the number of prescribed ads (especially if you need to rewind or fast-forward), etc. I can't give just 1 star because the content is so good, but the app is awful.
