Tell Netflix You Want Sliders Back!
You can request that the show come back to Netflix here at their website: https://help.netflix.com/en/titlerequest. It'd also be a good idea to tell them on Facebook and Twitter that you want it in a better quality.
If you'd like to see the show rebooted you can sign the petition supported by Jerry O'Connell at www.slidecage.com/change
