There is a whole lot more wrong with Hartman than what that article mentioned. If you have the time, Saberspark made an excellent (and long) video about Hartman and his fall from grace.
Counter argument: sometimes our memory of shows is rosier than reality. Take Looney Tunes, for example. Some of those original episodes made fun of mental illness, PTSD, even suicide.
In other cases a rebooted show is absolutely stellar, like BSG.
I strongly disagree. Children have no frame of reference, they'll watch whatever is on. When I was young I watched a lot of Hanna-Barbera cartoons and they were made decades before I was born.
Are you kidding? Speak for yourself. I loved retro cartoons like Looney Tunes and the Jetsons when they aired on Teletoon Retro as a kid. Everybody has their own tastes regardless of generation.
Depending on your definition of reboot there's the live action Drake Bell as Timmy sequel movies, and the live action Paramount+ sequel series where the fairies go to a cousin of Timmy, then an upcoming 3d animated one in a few weeks. Live action ones are questionable if they count, haven't watched them but presumably the Drake Bell ones are a direct continuation, Paramount+ one might be a soft reboot depending on how much they reference old events. New one definitely does look to be an either soft or entire reboot though since Cosmo and Wanda help out an entirely new kid who seems to have no connection to Timmy, though there could still be references.
