Warning, firstly, I do a lot of research at work, and often I find myself like this character having data that supports views that I do not like. So I identified with the main character also because I found him to be a nice guy. Maybe that is partly why I liked the movie so much. This may not be the same with you.
Overall, I thought the story was both good and original. The movie starts off that the hero's horoscope predicts he will have a great day, a 5 star day. The day turns out to be a disaster. Needing a subject for his course, he decides his subject will be to prove that astrology is nonsense. So off his adventures start as he goes and interview's people who have the same star sign as he does. It is a light story, but it does have its moments. I did like his speech that we make our own future.
The characters were good, interesting and believable.
The acting, I thought was very good. I liked everyones' performance.
The filming was good too.
Would I see it again, probably not as I have seen it, and it is not that deep that I feel I need too, but I do recommend it!
