I have finished watching the second season, and as written before, I have mixed feelings. For one thing, I do think that Daredevil works better as long as it's rooted in a "realistic" world without mystic elements. But ironically, the season only really kicked off after Elektra and the Hand were thrown into the mix.
The ep "Seven Minutes in Heaven", with the Punisher fight in the prison, was perhaps the moment when the season changed form "meh" to "kinda good".
It still lacked what made the first season so special - the origin story aspect which made the characters stuff way more interesting.
[...] Punisher was really the star of this season, in my opinion.
