Their documentaries are boring, insipid, and wasteful time fillers. I never watch them except if I am interested in the person they are covering which is very rarely.
I hope they are serious about more news and commentary. That will add to their appeal. I like having a larger mix of news and commentary to choose from since competition makes shows more exciting. Although I like FoxNews a lot, sometimes the formulaic presentation of their commentary shows is a little boring since I like hard news and what it means for all of us.
You won't be seeing them much longer. MSNBC recently fired their entire pseudodocumentary staff.
