The first episodes (especially the pilot episode, duh) of this series are quite slow and a bit boring. If you have patience enough to go through them, episode 6 "FFZT" is where it pays off. This episode is really good and shows the show's potential. It's got emotion, good character interactions and positive character development, which you will see more of in the rest of the series.

I love Agents of S. H. I. E. L. D. now but I can admit I didn't do so when I starting watching the first few episodes. I almost stopped watching in the beginning. I didn't even like Agent Coulson at first (!) Well, after 6 episodes that changed. Very good. It's nice when you can go from not liking something to liking it. It's a positive development. (I also didn't like Tony Stark until Infinity War basically).

I can add that when I was a kid I used to watch X-Files and Star Trek: The Next Generation, and I think this show took some great inspiration from both of those. AoS is way, WAY better than X-Files for sure. I'm not sure it's better than TNG (the best series made in history) but it's close.

Currently rewatching!
