He appeared in some good flicks and was likeable enough.
As far as his acting skills, well, it is acting. Not exactly a rare “talent”, seeing as how everyone, be it a kid, singer, rapper, etc., can handle the gig.
When people state so-and-so is a great actor or actress, what they almost always mean to say is, they a) like how he/she looks, b) like the actor’s natural mannerisms, etc., c) they dig the dialogue (very rarely written by the actor), d) they really enjoy the movies he or she chooses to pursue inclusion.
Very slowly the Hollywood myth of “great thespian art” is eroding.
A majority of folks can act with reasonable authenticity. And the margin between absolutely competent and “great” is almost always movie, script, direction, and editing.
Anyway, that’s my rant.
