The effort by the director and cast is admirable. But it's a trope that has beaten on over and over again - The cancer love story. The plot is bleak and the characters weren't captivating enough. Too many cliches, too predictable. The typical life of a cancer patient is depicted poorly too.
It's basically a short-fallen attempt to invoke emotion in the watcher and the execution could have been better.
Again, Kudos to them for trying. Making a movie is not easy task and their effort is respectable.
