tbh this would've been much better as a movie

I heard that this was supposedly a movie but Netflix or idk who insisted it is made as a series instead. nevertheless, it has amazing casting, acting, and cinematography, bae doona + gong yoo (never thought I'd need these two in one screen) the CGI is pretty good, not amazing but also not terrible.

also, why does lee Joon always have to be a villain *sighs* but I agree he's perfect for the role + luna is so pretty and cute!!!

overall, for a Netflix kdrama show, this was pretty good, it has slow pacing but is not boring. So, if you are a Sci-fi lover and if you're okay w/slow burn dramas. then I'd say watch this show.

At the end of the day, it'll all comes down to personal preference whether you'll like it or not. and for me, I actually like it, not my favorite but I like it bcs it's so different from the other kdramas which is enough for me to get my interest to watch it.
