Fringe Great Plot but more Comedic Relief

"Aren't you glad you got the car washed" was the only line in last weeks fringe that made me laugh. There needs to be more lines like that because in order for a normal human being to be able to deal with all that blood and violence comedic relief is necessary. Yet so far the plot is great especially the threads that are moving throughout the series the one on John Scot. It keeps me on the edge of my seat. However, character needs some work. The main character we are focused on Olivia Dunhum is too stiff and lack of a social life makes her flat which could make her hard to relate to or understand for the audience. I find her a little dull like she's just a vehicle that we are seeing on these things through which in some ways could work as long as the audience doesn't get bored.
