He is a teen ハート, 心 throb with a highly devoted fanbase who hangs on his every word.
He in fact is NOT a great actor, yes he is cute and charming but if あなた have seen him in もっと見る then one 表示する (Dawson's Creek, Dark Angel, Smallville, SPN) あなた will realize he plays the exact SAME CHARACTER on every 表示する he's ever been apart of. That is not a quality of great actor, and until he starts 表示中 some range outside of his comfort zone I will not change this opinion.
Now I 愛 watching Supernatural, I think its great fun and Jensen's default stage personality (quirky, charming, emotionally fragile badboy) fits in well with this show's dynamics so he's actually quite likeable. I just refuse to think he is "God's gift to acting" when he's your typical young CW actor.
