1 star: couldn't watch more than 15 minutes. Unwatchable, or language not as described.
2 star: jumped my way to the end for the ending. Unwatchable, but interested in how this turd ended.
2.5 star: I fell asleep, or closed my eyes for most of it.
3 star: watched it all, but not happy about it. Nothing better to do.
4 star: I watched it, liked it well enough. Would never watch it again.
5 star: Great moving picture show! I'll watch it again, and maybe again in a few years.
