The back story was far more interesting than the "current story" with the younger characters. The ending had a nice close out though.
Kaiju were scarce which is disappointing when the title is legacy of monsters. Makes me think we will see many and frequently. We only saw 7 during the whole show, 1 of them is Godzilla and total screentime of probably less than 5 minutes.
Episodes 6, 9,10 were the best ones in my opinion.
