Tezuka directed Godzilla vs. Megaguirus, the second Millennium film, and the Kiryu duology, Against Mechagodzilla and Tokyo SOS, the only Millennium films to be connected.
For me, Tezuka falls in line with Okawara as one of the more by the numbers returning directors in the series... Megaguirus is one of my least favorite installments, but I have come to like the Kiryu films more over time. I think they pair nicely actually, GXMG establishes the world and has some satisfying monster action, allowing GMMG to jump headfirst into the action, which is alright with me. Looking back, despite his blander faults as a director, I wish Toho had gotten him to do the 50th anniversary film.
Took me awhile to wrap this up, but make sure to check out my other Godzilla director threads -
Exterminate all rational thought.
