What I like:
1) Speed. For a lot of the pages on the old site, I only could "crawl" through them at a speed of Goomba. Now I can browse though it at the speed of Mario doing BLJ glitch.
2) Game resources page. I don't really like the design, but in comparison to what was on the old site, that is definitely better.
3) The user profile page. Finally I can reach my non/rated movie list without knowing beforehand that it is in "rating.exe" which was accessed from some weird locations. In fact, it is now much easier to reach pages you want to reach because navigation was improved greatly, mostly by text now becoming clickable links in places you were expecting it to.
4) Forum design is now the one with the site and seem not to require a separate login. Maybe I will actually use it now.
What I don't like:
1) Link color. On HP Pavilion Power 15, it looks just black. It is only sligthly visible on my other devices. Also, links that were navigated to are no more distinct from unvisited pages because default link is purple which is "been to" color at the same time.
2) Mario and Luigi at the top of the screen were removed. I chased them too much with the cursor to not notice. Not critical, but noticeable.
3) It was 2021, 1920x1080 is totally not the biggest resolution one can get... And by some reason, the new site uses about half of that res' width. Specifically, only 1110 pixels. Old site had only 10 pixels on each site as a padding and it was great.
https://tvtropes.org/ has and option called "Wide Load". If there were some logical reasons behind limiting page width, at least consider full width as a toggleable option.
4) Blue gradient at the top of the page lost some saturation. With new color it can be just safely removed then - aforementioned laptop barely has this color at all. But I would prefer to leave old color. However, new color looks better on mobile.
5) Publication button in a publication is obsolete. You are already at the pub, clicking the button does not do anything.
6) I can't find embedded video module. At all. I just don't like opening youtube site and would then instead download movies locally.
7) Tab design. It lost it's personality. New site has… line of text as a tab, old one has an actual tab frame and color of active/inactive tab.
8) Rating page currently does not have column sorting like the old one did.
9) (minor) New rating system with 0.5 steps instead of 0.1.
