Anyone check out the History channel's miniseries 'The World Wars'? I believe it initially aired in May.
It's a 3-part series with each episode lasting 2 hours long. It wasn't too in-depth being that they were covering approx. 30 years of history in a 6 hour span, so the true WW1 & WW2 history buffs may not enjoy it as much, but overall I think they did a good job with it.
I particularly enjoyed episode 1 where they highlighted the WW1 roles of leaders like Patton, Mussolini, Churchill & Hitler. Those guys are better known for their prominence in WW2 so it was interesting to see how they fit into WW1.
One thing that I didn't know is that Hitler could easily have been killed in WW1 but a British Private spared him and let him flee because Hitler was wounded & weary and posed no threat. Crazy to think of how different history would be had that Private pulled the trigger.
