Very good sci-fi show. Gets very realistic. Amazing VFX/CGI. But there are a few things I dislike very much.
1. Character development and casual conversations always happen on bar scenes. Gosh there are so so many bar scenes it's tiring and frustrating to watch. Stop at X space station, go to the bar, you are at an asteroid, go to the bar, welcome to Mars, here have a drink. It's almost predictable.
2. The actor who places James holden has a flat face. There's a limit to how many stupid decisions one can make. Many times I felt the plot was driven solely by stupid decisions made by the lead cast. The crisis that is given so much importance at a start of the season just vanishes at the end and a new bizarre plot is revealed all too convincingly.
3. Earth and Mars Navies are praised at the inital seasons. But in the last season they're all too busy shooting asteroids? Really? Are you going to disregard armies of planets just by this stupid explanation? Unbelievable.
4. Last season ended ubruptly. Could have made more seasons.
