The only problem is when there is a confusion as to which version is on TV, like with "Total Recall" and it's re-bake (a cross between a re-boot and a re-make)
I imagine it's about creating a "franchise" with toys and so forth, hence it will be awful since no decent director would go near it and it's bound to pull every punch so as not to offend.
But it really has no effect on the original, we've seen this over and over again. If anything an original gains from comparison to an icky reboot.
It's like whenever The Fog comes on TV, I think "Cool, I can watch this again". And then it turns out to be that sh!t achingly awful remake version. I can't reach for the remote fast enough.
