I noticed an advert on TV advertising "unmissable" shows coming up. MS Word marks it as a spelling mistake, but the Mac OS is OK with it.

I don't particularly like it.

You probably have to update your MS-Word. Unmissable is a word that can be found in most dictionaries. It is a pretty boring word but we can't deny the fact that it is used by some people.
