Kaiju Fever: Son Of Godzilla (1967)

The second Godzilla film in a row set purely on an island location, Son of Godzilla and is a light and fun entry aiming to be more kid friendly. The film introduces Godzilla's son Minilla a horrible grey lump of rubber, that is far from the ball of cuteness it's meant to be. The Kamaracuras' and Kumonga on the other hand look great and are one of the films best highlights.
It's a just simple fun kaiju movie, with some enjoyable monster action. Nuff said.

Kaiju fever: Ebirah, Horror of the deep (1966)

Here the series takes a different turn with the first of several Godzilla films directed by Jun fukuda. A much more self contained movie than the rest of the series by being set on one island location, the film was originally written to star King Kong but instead got replaced by Godzilla, which is why in the film Godzilla acts more like King Kong than himself. Despite this I still think the film is still pretty fun, the plot is pretty enjoyable and the monster action is entertaining too and I think Ebirah looks pretty cool. It may not feel much like a Godzilla film, but it's still a fun watch overall.***

Kaiju fever: Mothra vs Godzilla (1962)

The 4th film in the Godzilla series and one of the best featuring fun monster action and really enjoyable human stuff. Revisiting similar elements themes found in Mothra particularly that of anti-commercialism as the human antagonist try and profit off Mothra's egg much like the villain exploits The Shobijin in Mothra. So Plot isn't the most unique but it is still really well executed, in fact the whole thing is just solidly made with good pacing, acting and action (some effects are a little dated and hokey but still fun) leading to a really entertaining watch.
A great entry in the series.****

Godzilla vs Destoroyah (1995)

The final film in the Heisei series and a good one to end on. I think the movies main strengths are its little creative details, I like its links with the original movie and whole concept of Destoroyah and Godzilla's internal meltdown is really interesting. Also the costume designs of Destoroyah look great and the monster action is really good. A very solid Godzilla film  indeed.
