The first season actually was perfect. Blending nostalgia, suspence, romance, humour and horror perfectly to create an instant classic and earning a huge fan base along the way. The characters were brilliant and complex, and all of them had their flaws. Unfortunately as the series as gone on, more and more cliche characters have been introduced and too many are the simply for comedic value. Reactions and lines of dialogue feel cheesy and forced for a quick laugh but few of the jokes actually work. Some of the characters have even become caracatures of their past selves, rather than growing in line with the the horrors they've witnessed. It's still very watchable but unfortunately not without cringing multiple times per episode...
