Be aware this will probably be controversial
I'm content with Nickelodeon airing many movies I just really wish these movies had more variety, some family movies would be wonderful not all brainrot CGI baby movies like Trolls and Boss Baby stuff but y'know, variety.
Nick Jr should come off at 2 pm / 1 pm depending on time zones because that's close to the time kids get out of school plus we don't need it on weekends, Nick@Nite should come on a few hours later coming on at like 11 pm / 10 pm depending on timezones and should have more than 2 shows, I hate how Friends is the basically the only show here, there is more popular adult shows that could play, Nick@Nite should come on especially late on Friday and Saturday night.
Many people are highly agitated at Nickelodeon for their treatment towards Loud House because an episode and a movie of it was going to play on Labor Day but was scrapped, people get mad and say Nick has no variety but honestly I'm fine with this, I see it as the show getting karma for ruling the network for years in the past. It still airs new episodes so it's not that big a deal but that looks like about it except special occasions. The same goes for SpongeBob too with the overplaying, it was cool in 2023 actually getting to see SpongeBob in the afternoon for once but it's long since gotten old now, I'd like to see more acquired shows, some oldies would be cool as well. A weekend block airing old Nicktoons would be really cool and I can't think of much else. Maybe lose most of the live-action shows, they're dumb but make more of those game shows, it's what got Nick big to begin with.
