All too often when doing a remake, the creators do not think about why the original was so popular.
This is a classic example. All the way down to the theme song, they tried to make everything more modern to appeal to a new audience. However, this is a new generation with totally new ideas and thoughts. You can not just us an electric guitar to play the old music, you must either use the old or write a new piece.
The same goes for the episodes. The ones that were amazing for a generation ago will not have the same impact on this current generation. It is just a simple fact.
For that reason, this show did not succeed. It would have been better for them to simply rerun old episodes, or try to start an entirely new show that was similar, like the Outer Limits.
I appreciated the desire to create another show of this style, but they really did not do very well.
