This is the first review I post at IMDb and the reason is because Agents of S.H.I.E.L.D. is that good. I haven't even finished the 4th season but still, starting this series has totally worth it. Now if you love Marvel as much as a lot of people do, is a must watch. First season is amazing and it helps a lot to understand some references of the main Marvel movies. In the second season you'll get to see more sci-fi stuff, because of the Inhumans. The third season starts with a portal to another planet, and still talks a lot about the Inhumans because they're being hunted down. The fourth season is just epic, nothing else to add. Now, the performance of the cast, for the 6 main characters, it's just brilliant. You'll fall in love even with the villain. That's it.
