I wasn't familiar with this animation prior to buying seasons one and two on DVD, and I found it for a great bargain price on Amazon.
Having seen both seasons now, I can honestly say that the series started out quite nicely. Season one was exciting and quite good, especially because of all the fights and huge monsters (Megalos) that were in the first season. And the first season is well-worth watching. But then season two came afterwards, and it was a drastic change of pace and events. Where season one was action-packed and exciting, season two turned into a daytime sitcom instead. In season two gone were the constant fights and huge monsters. Season two is still enjoyable and watchable, but it is a major step down from season one.
The characters in "Is This a Zombie of the Dead?" (aka "Kore wa zonbi desu ka?") are all lovable, detailed, rich in personality and details, full of energy, individualistic entities and all important to the storyline.
The series should be watched in the original Japanese language. I never opt for a dubbed language track if the original language track is available. And true to the Japanese Mangas, the language track is as wacky as the animation itself.
I started out very much enjoying the episodes in season one, but hand on Heart I must say that season two brought the series down into mediocrity, which was a real shame.
A fun series that has lots to offer, just a shame that season two became an anchor around the series and dragged it notoriously down into mediocrity. There are some great moments throughout the series, both in season one and two. Worth a Watch, for sure, just take into consideration that season two is nothing like season one.
