I'm only starting to watch season 3 of Red Vs Blue and I can't get over how funny these folks can really be. The writing is good, the acting is bad, the graphics suck, but it is definately some of the best entertainment available!
I think I only previously saw season 1, and I think I missed season 2 entirely. Fortunately they sell the DVDs. I might have to pick them up.
Unfortunately my wife doesn't get their humor and hates it when I watch Red Vs Blue when she is home. Her loss.
