If you are not watching 'Eureka,' then you need to. The premiere of season 4 took us back to the swinging 40's where we get to meet another fantastic mad scientist Dr. Trevor Grant (played perfectly by James Callis). However, time travel has its consequences. What I love about this show is that the timeline changes and that's that. There's nothing they can do. A different show would have tried to "fix" the timeline, not 'Eureka.' Eureka is officially the best show on tv...at least during the summer. And it's a show that the whole family can watch. To boot this season Gais Baltar has joined the cast. How great is that?
