Probably for the ones I haven't watched.
But daredevil is fantastic, and legion is okay(better than these 3 mentioned)

I'm not a fan of these superhero series... I couldn't tell you about iron fist, Jessica jones etc. because I've never seen them.

correct order is to watch even numbered episodes first, odd episodes afterwards

First 2 seasons of Arrow are watchable.

Flash first 2 seasons are too.

Nothing special though.

They get much worse starting season 3 on.

That's the best most of these superhero shows can go for
"Watchable"

I think the flash is really good. I mean obviously the storyline could be stronger, but doing a weekly show format is pretty hard. But if you look at the characters, Grant is just a perfect Barry Alan. He brings something to the show that makes it feel like the comics come to life.

I don't think any of the other comic book shows have ever really done that.

I watched them week by week so it was kinda in order or airing

I dropped all dc shows but Gotham.
