I have to be honest, when I first heard about a Total Recall remake I had a wave of dread wash over me, remakes rarely turn out much good in my opinion. TR, however, isn't that bad... it's not brilliant, but not not bad. The worst thing about it, for me, is that there's no "Mars" in it, Mars has for some bizarre reason become "The Colony", or as we know it, Australia - and you have to pass through the Earth's core to get there... weird.
Other than that, I can't really fault it too much, it's really typical of todays "action" genre, lots of shooting, fighting and explosions, and it's all done well. The actors are great, the female one's especially are more kick-ass than the one's in the original, again in my opinion.
Just go in to it with an open mind, esp. if you're a fan of the original, and I think you'll like it.
