where to find chess games that have commentary

Are there any games I can add, and read a professional chess players commentary explaining why a move was good/bad?

There is a a whole section in lessons providing reviews of famous master games.

thanks @justbetfair I dont like the video format though, I'd rather see written notes about key moves in a game, is this possible? 

Well they have 15+ years of instructional chess articles here.  I always loved the articles by Jeremy Silman.

Thank you

There are many great books where the authors explain games:
Zürich 1953 - Bronstein
My Sixty Memorable Games - Fischer
My Life and Games - Tal
My Great Predecessors - Kasparov
Test of Time - Kasparov

Thanks but I'm after games that have commentary added to them within the notes.  I can't believe this hasn't been done.

You can also go to ChessBase, e.g.

Not sure what you mean. The games in those books DO have commentary added to them within the notes.
