Why is this movie so good?

Watch it. The first time I found it really boring, but then I just sat through it. It was boring, BUT it had a pretty decent plot. It could possibly show how much hardship, an inventor has to go through, in present time.

Actually for me, it was more because Bradley Cooper was in it. Technically, if it was so unbearable that I had to sit through it; I could at least see him acting in it.

Because you just think it's a good film while you haven't seen it. Watch it!
