I like all of Masaaki Tezuka's Godzilla films, especially the Kiryu Saga. Choosing between GODZILLA X MECHAGODZILLA and GODZILLA X MOTHRA X MECHAGODZILLA was extremely difficult. On any given day, depending on how I feel (or what I want to see), I may 'like' one more than the other.
However, I tend to lean toward GMMG due mainly to the epic kaiju battle that dominates the heart of this film. The three way knock down drag out fight between the titular monsters is one of the best I have seen. Also, the SPFX in GMMG are amongst the best of the series. But, GXMG had a better, more moving human sub plot, driven very well and convincingly by Yumiko Shaku's Akane. And I love the spectacular fight between Godzilla and Kiryu leading to a visually impressive and satisfying ending, one that left the door open for a sequel. So, it's hard to choose between the two films.
â€œGodzilla is a force. He is not something that can be stopped by human weapons. He is brutal and severe. My Godzilla will be the cruelest and fiercest in the history of the series.â€
