I finished season 1 a couple of weeks ago, and I have to say I was oddly mesmerized by it. At times it's not so much Ferris Bueller, as it becomes 90210, but it never failed to entertain me. All post-apoc tropes you know and love are being revisited, and the intro sequences are getting more and more creative throughout.
Also, the flashbacks get zanier throughout the series (with a flashback running through somebody else's flashback, who then comment: 'you weren't even here for this!'
), the 4th wall is frequently broken, and the story line, even though sort of bogs down a bit at about 2/3 through the season has enough turns and twists to keep entertaining.
It's probably not everyone's cuppa, but I was thoroughly amused and will certainly be checking out season 2 (if only because the finale's ending was quite the 'Whoa' moment
)...
