Review length question

My review is not accepted, because it is too short. The problem is that the remark "Sorry, your review is too short. It needs to contain at least 600 characters" is there before I begin to write!!

The film I want to review is this and here is the review I want to post:

_________________________________________________________________________________

Rather an adventure than a crime film

I have seen other crime series, like [link=tt0094525] and I found them more interesting than this film. Poirot as well as [link=tt1734537] had to solve really complicated cases, the were true detective stories. This film is dedicated more to action/adventure than to the solution of an unpredictable crime, by using a detective's capabilities.

I am rather disappointed because I like Sir Arthur Conan Doyle's Holmes, especially when portrayed by Jeremy Brett.

My vote 6/10.

Please note that I have seen reviews already posted containing some ten words. What's going on? It's not the first time I am posting a review, but is the first time that I see it a  priori found as too short!
