Gate is basically an jietai (SDF) in a fantasy world setting anime. Dragon vs guns! What more do you need?
The art is very inconsistent like Arslan and I hate how big the eyes sometimes get. It feels like there are two different artstyles in the anime. I wish they had the budget of Danmachi cause there are a lot of scenes that could have been really beautiful.
Yes, it is a harem anime (when is an anime not?) but the good news is all the characters have a purpose to the story and are not there solely to cater to every lowest denominator and the story moves at a very good pace. The harem could get way too crowded pretty quick though.
Love the Ride of the Valyries scene. Makes me want to play more MGSV.
I wish Gate had gone for a more realistic Berserk style but its a lot more mature than most anime. The writing really explores the premise in interesting ways. Very enjoyable anime for me. I can't wait to see what happens next.
