I'd say "Dear Frankie", a modest romantic drama, saves Butler from the pantheon of actors who've never made a good film. Now, Jessica Alba, she really hasn't ever made a reputable flick.
As for "Gamer", I almost don't know what possessed me to go and see it. My body wasn't taken over by a thirteen year old by who then virtually directed me to my nearest multiplex, so there must be another explanation. I reckon it was the Michael C Hall effect. I wanted to see if Hall could acquit himself well in a blockbuster, and yeah he was as good as could have been expected.
Butler's agency might find themselves getting kicked into the pit by the burly actor. They've not only scored him one of the worst films of the decade in "Gamer", but partnered it with the equally bad "The Ugly Truth". And in a single summer! I suspect some numerous razzy gongs are pending.
