Well you and the critics have different agendas.
Most people watch a show simply to be entertained. A critic has to dive deeper into it.
They have to look at story, writing, directing, acting, structure, art, etc etc.
Is Iron First entertaining? Yea. Mostly (so far for me at least, only on episode 3).
Is the writing good? Not especially.
Is the directing good? Not really.
Is the acting good? Mostly, (aside from the one bad guy's son) but they're not given much to work with.
Is the story very good? Not especially.
But is it entertaining? Mostly, yea.
So it's very possible for you to enjoy a show and a critic to really dislike it. They're looking for things you aren't.
Also, like I said, just on the 3rd episode, but if we could please stop using the phrase "I'm Danny Rand!", that would be great.
