The Best One
In my opinion of course, the best Marvel show so far is this one.
Well written characters, a fresh and original look and setting, a great lead character that does not need to be overtly sexual or bitchy to be strong (as in a lot of cable shows often try and have female characters be 'strong' by writing them as overly mean or overly sexual), and a reliance on fun, adventure and enjoyable characters instead of the dark, 'gritty' cynicism that rules television today and has become quite worn out.
Agents of SHIELD is just boring and cliched with poor writing and characters. Daredevil is a good show but way overhyped by the 'mature' crowd who are so excited to have something that's gritty and 'not for kids'. It's a good show but people act like dark and gritty = automatically better. Jessica Jones takes it further and makes out like drinking + sex + cynical self loathing = mature. Jones and Cage were both uninteresting characters.
This wins the enjoyment factor. Fresh, new, interesting and unlike pretty much all other 'superhero' adaptations. So of course it's the one to get cancelled.
