My very quick thoughts on HHN35:
Wife and I did our first kids-less trip Thursday - Saturday, attending HHN on Thursday. We bought Express Passes and showed up at about 4:45 PM to get our wristbands. We were able to hit Stranger Things and Hellraiser, as well as hit a few food booths before the gates opened shortly before 6:30 PM.
Express Passes: I don't think we waited more than 10 minutes for a house all night with express. It is well worth the investment. I know it's a lot of of money, but my wife is 32 weeks pregnant and wasn't standing in any long lines

I'm not a big rides guy during HHN, but the wait times all looked pretty short most of the night for the four rides at USF during HHN, so not sure Express really matters for them.
Stay and Scream: It seems like these updates are massive gamechangers, ESPECIALLY if you are someone not buying express. I can't stress enough, that if you aren't buying express passes, your night will go so much smoother if you attack Stay and Scream!
Rides : The rides are all good, but man, HRRR is sorely missed. I'd guess USF is going to push to get F&F coaster up by HHN next year. It's going to be awesome.
Diagon Alley: First year that I've skipped peeking into DA. With Butterbeer now almost $10, I've drawn my line in the sand. Soo good, but the price is nuts.
Nightmare Fuel : Been coming to HHN since 2019 and this was by-far my least favorite Nightmare Fuel show. No idea what was going on with the plot of the show. Seemed like there were less stunts/illusions in this show and not as many wow moments as year's past
Stranger Things Water Show: We made it through a minute or so of this before bailing. Seems like you can find better compilations of the series on YouTube.
Food Booths : A standout year for food, IMO. Fried pickles, mozzarella sticks, egg rolls, mac & cheese and jerky.. All great! I rarely drink and I'm too cheap to pay the insane prices for alcohol at HHN, so no reviews there
Scarezones : A down year for scarezones, IMO. My reviews are biased because we attended an on again/off again night for rain. As a Fortnite fan, WTF was that? Club Horror needs to go. Clowntown is actually a cool idea! The Art show (if we want to call it that?) isn't for me. It's definitely popular, the entire street in front of the stage was PACKED.

My review may sound negative but we enjoyed this year! Since coming for the last 7ish years, it would probably rank near the bottom, but was still fun and a good event! Relatedly, we skipped MNSSHP for the first time in that timespan. Another year of Hocus Pocus shows and repeat entertainment made it a skip for us
