Query: Disappointing

Some rave that this is just different enough from the original to make it entertaining. Well, it may be just that but it's not different enough from a hundred other modern action films to make it entertaining enough. The cast doesn't measure up to the original - nor does the environment. Mars made the original a real sci-fi film whereas this could take place anywhere on Earth. Here, this could be any one of a hundred different films and you couldn't tell the difference. Sure the effects are better than the original but not enough to win an Oscar like the original did. It's sad to see how easily entertained people have become in the last 20 years. Farrell doesn't have anywhere near Arnold's presence, who was surprisingly good in the first one. Plus he had the physical build to make it much more believable that he could take on big opponents.
