I finished off Iron Fist in a week. Honestly I wasn't interested in watching anything else until I was done with this. It's very similar to all the other Netflix Marvel series. If you like one you'll like them all. If you don't like the others this won't be the one that changes your mind.
I also like Finn Jones as Iron Fist. I'm tired of all these actors bulked up to pro wrestler level. In the comics Danny Rand has always looked small while Luke Cage looks huge. When they are together in the Defenders it's going to look a lot like the books
I only like Daredevil. NetFlix has much better TV shows to watch than Iron Fist if you're not really into everything Marvel makes.
