I have a ton of minatures packed away in boxes. I too was more of a painter than a player, even won a couple of local painting competitions
My armies include,
Space Marines - Black Templars
Sisters of Battle/Witch Hunters.
And of course it goes without saying..... Skaven
I watched the Ultramarines movies a couple of weeks ago. I think you have to be an absolute fanboy to like it as it was total tosh.
I have to admit though that everytime there was a close up of the the bolt guns or armour details I'd be thinking of how to paint it
