Minimum Number of Characters for a Review

1. I'm at nearly half "Your Review" box & still need another 150 characters (assuming a space is not a character). 
2. Why add time wasting as a desirable trait both for the writer & for the reader? 
3. You are forcing reviews to approach the "spoiler" stage.
4. Why reward prolonged, excessive wordiness when succinctness of thought is the desired trait. (We're not 19th century Russian writers with nothing else to do with our lives. Outside of Vodka, of course.)
5. Most importantly many movies are simply not worth the words (i.e. time). 
6. More is the desired goal? Sounds a lot like American consumerism. You're not a true American contributor unless you buy more & bigger. A true indicator of value is more?
7. To sum up (Am I at 600 yet?) I'm very disappointed.
