The thing is, we've had various ultra celebrated cbms in the past and this thing has never been an issue. Sure it could be better but just what is it you think of the films we have gotten. If you were ok with, why does the buck stop here?
Also, Hopkins and Redford are super celebrated actors and it's not like they are turning oscar work. I believe Glen Close is Guardians....Just what caliber of acting are we demanding from them...I'd say it's somewhere in the Gal range.
Yes Heath got a best supporting nod, but there is a reason why he's the only one. That reason hasn't stopped us from deconstructing what has been wrong with the genre for the past 40 years however. Will smith was great in ID4. Paul Walker was great in fast. Sometimes it's not about an acting class but rather embodying the character. I for one don't think Wondy is beyond Gal. Especially under Snyder's direction(tends to yield bold performances).
