Actually, I decided to not add it to my watch list after seeing an alien in the trailer. But since I like the military genre I changed my mind and watched the series to see how the story will flow. There is no impactful surprise in the plot, just something that you can guess where it will go. It wasn't that bad but not great either, something you can watch easily and leave without any hard feelings (but tbh I have a tiny for the last ep, it's just too bad for him to leave like that). And just don't look for any bit of logic from people in this series.
