I didn't think the incest thing would work neither. However the fact that neither of them was the evil guy's son surprised me. But then again I did miss a few eps in the middle when I was at uni, so that may be why. lol.
the ending kind of sucked. If they sticked with the incest problem it would be something interest. Incest is like taboo off series.
the special effects was goood. it was so obvious that they were not siblings. but the two brothers was surprise to me
I was trying to figure out what was happening (who is whose son?!!) and was glad the ending explained it all.
