The 100 started out as a typical&generic teen-show with a sci-fi background- luckily it's been worthwhile.
Season I-
average
plot holes
no character depth
felt cheap, kinda teeny
But!
Season 2-
shocking
huge quality jump
character depth
still kinda teeny
no major plot holes
Season 2 Finale episode wasn't longer than the rest, but it felt so...in a positive way! So much happened, interesting how the situation folded out in a way that is both, shocking and satisfying.
In my TOP list from now on!
