Of course, the new film can not be compared with the original film all in all. This particularly applies to the actor's performance. Is not that the power in the new Oldboy bad, it is in the original version just damned bloody brilliant and by all actors.
The film gets to me yet fully earned four stars and has a main reason:
it was great fun to watch the film and that's what matters.
Sure, the new Oldboy is simpler in its design, but it is also precisely in the respective scenes, so that we can understand the individual film sequences immediately. It is all in all easier "absorb" the appetizers. In the original film, it is not quite so simple, which acts much more massive in its ornate style and can be confusing.
Without giving much away: the remake and has managed all times worth seeing.
