You can check out my various reviews here.
And if you haven't checked out any of these shows, you really should. THE 100, especially, is must-viewing for fans of Ronald D. Moore's Battlestar Galactica.
And while you're at it, you should really explore Den of Geek, too. This sci-fi/fantasy/superhero-friendly website is bursting at the seams with coverage of movies, comics, video games and so much more. (I'm embarrassed to admit how much time I've spent on this site. It's addictive!)
