First of all , a huge thank you to Dramacool for uploading this movie, you guys never disappoint?.

When the trailer for this movie was released, with the top teir casts, I already knew it would be a hit! . The CGI was on another level, nothing short of perfection. 5 minutes into it, I knew it would be worth the two hours and 20 minutes that I'll spend on it.
The fight scenes were so real, a hit to the aliens and it felt like I was being hit ?

Kim Woo Bin impressed me the most, it was his first movie since his comeback on Our Blues and he is still as gorgeous as always. His acting skills got sharpened the most, that robot or was it Alien suit of his? Damn beautiful ?.

The alternating between 2022 and the Joseon period was done so well , zero room for confusion.

Kim Tae Ri was awesome as always, same with So Ji Sub and Ryu JY.

All in all this was fun and nothing sort of being perfect.

Personally I think Korean movies produced entirely by Koreans are a lot better than ones produced by Netflix.
