Completely unnecessary first three episodes that really sour the whole experience. And then? A good material that would have been a great study in sorrow and could have worked great as a short movie; but it is Marvel, so instead, they made it into this meandering, overblown mess that ultimately destroys its own message with idiotic final act. Because if there were just honest emotions instead of pointless CGI fights, the audience wouldnt enjoy it, I guess. Shallow, mediocre. A missed opportunity.
