The SFX would be upgraded in a remake - I can't see any American network buying a sci fi show that has less than reasonable SFX. Thats just the cost of doing business. My hunch is that this remake is even more in the same boat as Star Trek. To get anyone interested would require changes from the original and what changes are required will be driven by who picks it up.
The story says its being shopped to US networks. I hope they mean cable as well as broadcast. On broadcast, it will be a tough sell and even tougher if it gets to air. neilsens are dropping all over the place, not a good environment for any sci fi much less space opera type sci fi.
