Sounds like a good idea but it really depends on the quality of the documentary/informational shows... If they're anything like what Discovery/History/TLC/Science/etc channels have aired in the last 10-15 years, then it's complete rubbish.
From the promo screen grabs, it looks like they might be, but can't tell.
I've had this for less than 1 full day and most of that has been sleeping or at work. But from the few things I've looked at so far.
To me, it seems to be a lot like the old "Discovery Channel", and "History Channel" documentary type shows type shows.
I haven't seen any mermaids, bigfoot or reality shows yet!
