As someone who is actually old enough to have seen the original, with Carl Sagan, which I watched as a kid with my dad, I am underwhelmed by the new guy. That said, I am forcing my kids to watch this one. They really like it.
I love Neil deGrasse Tyson. But I recognize that he's no Carl Sagan. I'm glad your kids enjoy A Spacetime Odyssey - I've been full-blown enthralled with it.
Sucks. Like, needs surgery fucked up? Or just stay off it for a while? I still play basketball, and live in fear of the Achilles injury. See above -- I'm old. Fortunately, I don't move very quickly any more, maybe that explains why no major leg injuries.
Stay off it for awhile but if it doesn't get better you're pencilled in for a specialist in about 1.5 months.
