I thought that the movie was very interesting in several parts. How was it that Logan was in bed sick and yet self healing? Where did they get their mutations from? It would stand to reason that if they both had the same mutation that one of their parents would have exhibited the same. The conflict with Logan and his brother was good.....showing a good man vs a man who lost crossed the line of good in to evil .Special effects were great. I didn't think that we needed the headless villain to show his ugly head again. Sometimes a death should remain that....and acid bath would have helped. Striker was a good bad guy too. All in all a good movie worth watching again.
