It's a bit soon for a full reboot surely? Lost was great but it didn't end particularly well (though not actually the WORST), and it had some other issues (FAR too much focus on the Kate / Jack / Sawyer triangle that was fun for the first season and then boring). Also a few very promising characters that were introduced only to disappear without ever living up to potential.
But it only ended a few years ago
. I think 15 - 20 years at least before a show is rebooted. I'd rather see a soft sequel exploring more of the concept. You could even bring back some old cast members for guest appearances.
I feel largely the same about The Matrix. There NEEDS to be more Matrix, it's such a brilliant sci-fi concept and there is so much more to do with that world, but I'd rather see "semi-reboot" sequels than a full retcon reboot. The obvious way of doing so being to set it hundreds more years in the future with a new "one" emerging, and referencing the events of the original trilogy as canon.
