I'd say Jessica Jones had slightly more pluses than minuses, and for a marvel property, that's pretty incredible. Krysten Ritter was good not great, and Tennant was by far the best performance they've had as a villainous character.

That being said I liked Colter more than Ritter and was sad as he felt somewhat underused but alas shows about Jones not Cage. 

Either way though Defenders will almost certainly be the best Avengers-style Marvel propriety that Marvel makes.

P.S. The shows are always going to be better than the movies, because one is 2 hours and the other is 13.
