Peacebang started quite a donnybrook by using the word "blasphemy". There's little I can add to the controversy, but it does make me want to confess to my own blasphemy.
This blasphemy was the result of accepting a trial membership in Netflix. The first DVD I got was the 2003 remake of "The Lion In Winter", starring Patrick Stewart and Glenn Close. Here is the blasphemy: it's better than the 1968 original.
Now, my heresy doesn't go so far as to deny the divinity of O'Toole and Hepburn; let's all agree to say that the difference lies in the director's vision. In the 1968 version, Henry and Eleanor are played as archetypes, demigods- one can admire them, but not feel for them. But Stewart and Close made them human beings, real people who may live larger than you and me, but not larger than life.
The boys, too, are more effective in this remake. I can't say that any one performance is better than their '68 counterparts, but somehow they convey the dynamic of a bunch of brothers much better. I know, I was #2 of 4 in such a bunch.
As deeply heretical as this may be, if someone who has never seen the play or movie asked for a recommendation, I'd have to recommend the remake.
