Then we'd be spared remakes like Invasion of the Body Snatchers.Only movies (or TV series) that should be remade are ones that were never good to begin with.
However, Total Recall does have an idea which could be done better (and is of course based on a short story which could be adapted better), so there's definitely real potential for a remake.
As for Shia LaBeouf, I'll remind people the original film starred Arnold Schwarzenegger. How is this not an improvement?
) but I honestly don't know why he's as successful as he is. I find him painfully bland, to be honest. Arnold, on the other hand, as someone else said, has great presence and can simply be great fun to watch. And I will say that I actually think his performance in Total Recall is quite strong and one of the reasons (I think) the movie works as well as it does.
