Kristen Bell is still working on a Veronica Mars revival in the form of a limited-series run, but it may be a long-term project. Currently, Ms. Bell is tied up with The Good Place, while Veronica Mars creator Rob Thomas is doing a Lost Boys reboot.
Veronica Mars was revived most recently in 2014 as a film following a successful Kickstarter campaign. That film holds a 79% approval rating on Rotten Tomatoes.
