If you decide to develop this name -for a movie blog for example- do you really want to get stuck with this domain? Perhaps you will look at this domain later and wonder why you didn't use a fresh domain that you really like, for the same price. The danger with brandable domains is that people tend to get attached to it (at least i do sometimes) while often it isn't worth much.
In your case, I would look for more possible uses for the domain.
