I need to get hooked on immediately to continue watching a show. Else I'm out in not more than 15 mins tops. Iron fist is definitely interesting and worth a watch. Its entertaining and paced reasonably well. I must admit that some dialogues felt very immature. However, I assign these comments only to the first season.
In the second season, the characters nature changes. Colleen starts becoming more active, which is in no way related to her character in the first season. To make it worse, her acting is too lame and character show-offish. Joy turns into a completely different personality. Still pushed thru a couple of episodes hoping it'd get better, but couldn't carry past the 3rd. Dropped it.
