Has anybody watched the anime or read the manga? I started recently and have caught up. I like it.
Plot summary for prospective watchers/readers:
100 years ago, giant creatures (generally ranging up to ~15m tall) known as "Titans" appeared and wiped out most of humanity. They appear to be mindless creatures with the sole purpose of devouring people, and they have regenerative capabilities that render conventional weaponry ineffective.
The surviving humans somehow built 50m high walls to create just one (large-ish country-sized?) territory that was safe from Titan invasion. There are actually 3 walls in concentric circles, with the poorest people living in the outer ring of course.
The story mainly follows a trio (and their peers) as humans continue to unravel the mystery of the titans.
As the series begins, an enormous titan taller than 50m appears and kicks a whole in the outer wall, allowing other titans to invade and just wreck things everywhere. Tragedy strikes the main characters. Fast forward a few years and they have trained to become titan-killing soldiers.
