Just finished watching and I LOVED IT!! It has my two favorite things: Space and Doh Kyungsoo :3 My review is probably a bit biased because I'd enjoy a movie with Kyungsoo just sitting there doing nothing for 2 hours lol but I really enjoyed this! The plot was pretty typical of a space movie (The Martian vibes) but there was never a point where I was bored and I actually cried a lot lol.

Like everyone else is saying in their reviews, the CGI is amazing!! I've never seen a Korean film with this good of CGI (might just be inexperienced though). The acting is also amazing! I loved Sol Kyung Gu as Kim Jae Guk and ofc Kyungsoo (I'll get more into his acting in a sec tho lol). Overall, I definitely recommend watching this film!

(SPOILER WARNING):
One thing I didn't love (but not a huge deal or anything) was the typical english acting lol. I just always find it so cheesy and the actors they chose at NASA were so stereotypically American it was hilarious (especially the big boss guy who keeps trying to sabotage the rescue mission (dad from the Incredibles vibes). Kyungsoo did amazing with his english lines tho omg <3

Now onto the most important part: Kyungsoo's acting <333 he is such an amazing actor, he really pulled this role off spectacularly. I sobbed my eyes out when I got to the part where he almost gives up and turns the oxygen valve off ):: His acting is so convincing, I could sing his praises endlessly!!!! I'm soso proud of how far he's come and I hope to see him in more dramas/films in the future.
