Here is my review without any spoiler: The Punisher starts very promising like most modern series nowadays, the action scene are great the story promises utopia with some prominent mysteries (especially if your new to the Punisher story), then after 4-5 episodes it all start trembling.

From the beginning it seems there is a schism in which creator wants to tell a Marvelish super-hero style story like most the series from Marvel yet it insist on more serious fictional tone, from this perspective I can say something like Homaland or Banshee, sound great isn't it? yes if you can completely execute it. The series such as Homeland, though not flawless, but telling a very serious story in the manner that you will convince that what the story conveying it really has happened, however The Punisher hasn't accomplished this feat to any extend.

I think this is the major problem with the Punisher and the result is unconvincing story plus very poor execution specially in further episodes. Without any spoiler let me give an example. Like majority of superhero films the law enforcement in these movies should be impotent to make convincing scenario for the hero to act as a savior, this is the foundation of any superhero movie, however in the Punisher the the law enforcement are joke and I am talking about all of them FBI, Homeland Security, CIA... and that's make the events surrounding them insubstantial which are most of the them, the result is some banal action scenes with unjustified events which are against the serious tone of the series.

Even though the story regularly become naive and unrealistic the only eminent element of the series is the frank castle itself. Jon Bernthal act in one word, is extraordinary, I have to say he is the best choice for this role yet I think it wasted poorly, even I like Ebon Moss-Bachrach (David) act, unfortunately I can't say the same for other actors.

In conclusion the Punisher is a mix of shallow storytelling, that to the viewer eyes makes the significant events of the story somehow trivial and small, albeit some great acting and some meh action scenes that gradually become boring.
