I made some comparison screenshots for context

In general I don't like the whole max-width centre-aligned look of all the new pages; in combination with the additional padding and whitespace on some pages like the submissions page and the front page, it feels super cramped and noisy to me.
I do like the new colours, they're pretty sexy, although questionable choice for colour blind safety.
I like the new movies and articles pages, they're presented a bit cleaner in spite of being similar and using more whitespace. I like the new game resources page a lot, it's probably the page with the greatest improvement, bravo there.
I think the submissions page is a big downgrade, you get many fewer results visible on screen, the max width is causing unnecessary line wrapping, the date is using weird-endian instead of the ISO standard big endian format (front page too), and I found the filter more confusing to use than the old one.
I like the new news page, I think the separated rectangle containers work better than the horizontal line dividers, and I like how the post dates are in a faded out colour.
The movie page is considerably worse, the list of well named downloads was much better than the sprinkles of links with weird names, and the presentation of keeping those links and categories separated from the prose was much cleaner, and used the horizontal space better. There's no more "similar movies" anymore? Also it looks a bit weird giving the title of the movie twice like that.
The new forums look like what happens when a CSS file didn't load, they're
fine, but man what a downgrade, no images, no dates of last posts or any indication that there are no posts anywhere, super cramped, no access to primate messages or a search function.
The loading times are fantastic, pretty damn happy about those, I do miss the cute little animations in the top banner, but I can live without them no problem.
One last thing I noticed, the featured movie on the front page has a scroll bar; I think it's an improvement over the ellipses of the old site, but the one I happened to get a screenshot of looks very unfortunate, I dunno if there's anything that can be done about that though. Also there are no stars in the new front page, I like stars :(
Good work all ground, I like both the old and new sites, and so I have mixed feelings about the redesign, wouldn't say it's any better or worse than before.
EDIT: About HTTPS, doesn't using it prevent caching? Like if the site goes down, I can't even use my browser's last observation of the page. If so, then using it for anything other than the login page seems like an anti-feature to me...
