This is a good movie. I won't go into the plot details much, there's nothing astounding or mind blowing.
The movie is a quasi-hipster movie about people finding themselves by addressing long-overdue personal and inter-personal issues.
The thing that sets it apart is that the main cast of characters have some form of mental issue. The secondary characters, who also play a large role in the film, have their own issues. It's interesting because not many films address how mental illness affects family and other relationships. Anymore information, I feel, would be spoiling parts of the movie that are better for people to see for themselves. The trailer gives enough info about the movie.
I think the people who won't like this movie are people who don't like depictions of mental illness that aren't 100% accurate. I thought they did a good job with the characters (for a movie depiction anyway), but people don't all act the same way if they have a particular mental illness. So if you're looking for 100% realism (or more accurately, your idea of 100% realism), you probably won't like the movie. Basically, anyone trying to "relate" to the movie in any sense beyond the basic human experience won't like it. It's not for professionals looking for perfectly accurate depictions, is what I'm saying. Because there are none. People are different. But it's still a good movie.
And people who hate a certain level of realism may not like the movie. Some of the characters are treated or thought of negatively because of their disability. The movie doesn't get into that too much, but that was one of the elements of the movie that made it interesting to me (because of character interaction), but finger-waggers may say "That's not how you treat people with a disability! That's not how (person) should have handled it! This whole movie is bad now!" So if you're a moral superiorist, you may not like the movie.
If those things don't apply to you, and you want a good drama, I recommend the movie.
Also, I bet you're wondering why the title of the review is The Road WITHOUT, eh? Sounded catchy, amirite? Yeah, I got nothin'. I'M SORRY!
Good movie though.
