The problem with 600 character limit in User Reviews. Have you noticed these?

​Hello, as a regular movie reviewer, I have been struggling with 600 character limit that was put one or two weeks ago. But today, I realized that I am not the only one dealing with that. I was reading recent reviews from some other users and found these:​

​I am not reporting them. Please don't remove their reviews. It will be very discouraging.​

​On the other hand, this one is from someone with over 4000 reviews. It is slightly over 300 characters. Check the Likes he received. It is listed #1 in "Featured" ranking. ​

​I just want to tell that sometimes there is not much to say about a movie or you can express all your opinions in less than 600 characters. Don't you think it is a bit too high? Why not reduce it to 300 characters for example?​
