Should I start reviewing movies?

Lately, I've been toying with the thought of starting a series of articles, where I do reviews of both good and bad movies. In my line of work, I come across various media products, meaning it's a part of my job to watch a lot of movies. :)

So I was thinking I should review some from a meer professional approach, but in a light, straightforward and not too lengthy fashion.

What do u guys think?
