Is character developement to much to ask for?

Lately I have seen a few movies where the action was good the story OK but you didn't learn about the characters in the film. Which I don't know about you but for me that is very important (among other things like ending a movie properly lol). you could have a great story but if you don't draw your audience in with characters they learn to know and get attached to your story is going to miss the mark.

SPOILER ALERT!!!!    SPOILER ALERT!!!!

For instance I just watched The Warrior. Really great fight scenes but you didn't understand why anything was going on. Like why did the brothers not talk? why was the teacher losing his house? Why did the brother in the marines go AWOL? and why if he hated his father so much did he go to him for a place to stay? so all in all not a good movie for me. (and yes for those of you who are going to say I just didn't get it) yes I know they touched on all those subjects but I mean they barely touched them more like grazed over so fast you didn't get the depth of it. it just skimmed the surface I am just saying I like my characters with a little more depth.
I have been having a really hard time getting excited about movies lately. They are just lack luster lots of big booms , fire , and fights but really nothing deeper then that. I want an experience (I don't know about what you want I can only speak for myself lol.) I want to be sucked in and emotionally invested in the characters and the story so if one of the characters goes and gets himself blown up in one of those really big booms I will actually care. So writers please take the time to create not just excitement but a more whole and deeper picture we are not all morons I promise it won't go over are heads. Also if it is based on a book (which now a days is a lot) please DO NOT assume everyone has read it and include the little secret details and information so we understand the joke or information (like the mauder map in harry potter I had to explain to my husband how the hell professor lupin know how to use it lol) to me that is important info just saying.

Moral of my story put a little effort into your movies and maybe people will actually buy the DVD...
