Once in a while, you stumble on someone great like Kiefer Sutherland. A great actor is able to transform an average TV show into something more than a TV show. I think Kiefer Sutherland in 24 fits this description.
Know I know that not everyone would agree with me on this but 24 is really not that great of a series...it would be worse without Kiefer Sutherland in it. His acting skills can be summed up in one word - superb. In fact he's so good that I have trouble separating the awesome protagonist from the drunk who went went to jail for drunk driving. To sum it up, without Kiefer Sutherland I'm just not sure if 24 would be as enjoyable as it is.
