Thumbs up:1. the overall special effects, which I thought looked quite good. As always there are those sequences that could look better but taken as a whole the effects get it done for me.
2. the bulked up appearance of Godzilla in this movie: the monster is a barrel chested, 100 meter tall juggernaut and the high speed filming, used extensively in this movie, as well as the audio effects used for the monster's foot steps, both help project the monster's size, power and intimidation "factor".
3. the ship of the Futurians: domed and with a pulsating, strobe like pulse flashing along the bottom part of the craft, this ship indeed looked like something from the 22nd century
4. Anna Nakagawa, who plays "Emi Kano", for simply looking gorgeous

5. the effects of KG's gravity beams: KG's beams look terrific and their effect on anything they come in contact with is devastating, buildings blasted apart in often spectacular explosions of debris
6. the two battles between the monsters: a nice combination of close in grappling and beam exchanges. Both Godzilla and KG use their respective powers to full use: KG uses his greater bulk to try and stomp down on Godzilla, as well as trying to strangle Godzilla with one of his necks. Godzilla relies on his primary weapon, his oral beam, as well as his nuclear "pulse". I liked the battle between Mecha KG and Godzilla somewhat more because the fight took place in the city(Tokyo), the absolute demolition of surrounding buildings by these two monsters a reminder of the collateral damage their fighting causes
