I'm probably wrong; There probably never was a GONZO "before," "after," nor "during such-and-such time." I always thought that (after watching Trinity Blood, Glass Fleet, and Last Exile) GONZO was one of those good "art-house" companies (where Gainax and SHAFT were considered the bad ones). I didn't realize that it's so bad in Japan that it's anime industry resorted to catering to the shounen-hating, "2D is my girlfriend," anti-reality types.
With that said; Chrono Crusade is probably one of the rare attempts from Japan's anime industry at telling a story that's based on America and its culture.
It's a good story overall: Mostly hardboiled and "cop-buddy-themed," sometimes whimsical, a third of the time LOUDLY YELLING (Thank you, HillHaag and Greg.), doing its best "for the otaku" but realizing that it's a "serious, edge-of-ya-seat anime based in AMERICA." It didn't spawn as much fan-based h-doujin material like Saki did, but it counter-programmed like a Belmont slewing 100 demons. So yeah.
