Wait, wait.... what? Because he's a tv actor?? Loads of a-list actors are doing tv-shows these days, tv is not the bottom of stardom as it was in the 90's. Look at shows like True Detective for example. No, him coming from a tv-show is definatly not something to be held against him.
All I care for is a good actor, and every article I read talks about Boyd as a good and solid performer on Narcos. Never saw it myself, not my show. But if you think a big name is more important than a solid actor, I think your priorities are askew. Just because someone's a big name, doesn't make him/her a good performer. Sure, Del Toro would have been awesome. But Franco? When his name was going around, I wasn't sure. Some of his stuff has been good, other things..... let's say not so much.
