This movie IS a comedy. There are many types of comedy and you don't have to laugh out loud the whole time for it to be a comedy. The movie is funny, charming, and very cute.
It really isn't about Ned's philosophy of expecting the best of others and seeing the good in them because even thought some people don't, and it can hurt you, more people do and everyone is better for it. It's about family dynamics, life choices, and learning to accept your own actions.
By accepting responsibility for your own actions you are able to free yourself to be more accepting of other people despite their flaws. Because we all have flaws.
Ned is less of a protagonist and more of a catalyst for change in his sisters' lives. The only reason I don't give this movie a 9 star rating is because the ending is a little on the weak side. They could have stopped the movie a few minutes earlier and it would have been stronger.
