What concerns? It's entertainment and speaks to each individual differently. For me, it's not about "thematic signature", Star Trek 2009
was about pure unadulterated nostalgia. For two hours I felt like a kid sitting in the theater. It doesn't mean its a film without flaws but it served its purpose for this individual.
I went to see The Hobbit
with my wife whose been a fan of the story since she was a little girl. It was more fun for me to see that film transport my wife into a world she always loved than the entertainment value I got out of it. From what I did pay attention to, it was a very dull, uninspiring experience. And for all the things I can count wrong with the film, it won't sway my wife's belief that it was an incredible film.
Different strokes for different folks.
