I honestly think Seuss Landing is really underrated and well-themed. I love all the Suessian architecture, how everything fits the palette and forms a curve or wave shape. It's got so many little details and areas that make it feel very filled out. The little Lorax garden, McElligot's Pool out front with the waterfall, Horton on top of the spiraling Caroseussel roof, the tiny door in that one shop. If I Ran the Zoo is a wonderful play area for the little ones, and the Trolley is a nice Peoplemover as well.
Cat needs some work. Some light spinning could help it create some energy during the more blank portions and some general love to the effects is needed. The animatronics are weird and goopy looking, the CG screen is hilariously bad, and there's just not a lot of that modern Universal polish anywhere to be found here. Despite that, I think the bones are solid and I think with some plussing like E.T's been getting recently, I think it could be a really wonderful dark ride. I do like this one quite a bit, even with all of the flaws.
Generally across the land, I think there is a feeling of...lack of upkeep, I guess is what I'm leaning towards? There are quite a few sections, especially areas on the outskirts of the land that don't get utilized by Uni themselves or walked through by guests very often, that feel dried out, grimey, and overall not well polished. The area behind the Hat Cat shop with Gertrude's egg is always covered in dirt and tree leaves, and there is a big wide area towards the back behind Cat and Fish that feels like it hasn't been powerwashed since the 2000s. Feels like an area that could force Disney's hand if it was within MSHI, it's that bad imo.
I think the biggest offenders for me with that lack of upkeep are the Seuss character costumes. They are built pretty okay, definitely built in a 2000s Universal-y way, but they work fine for what they need to do. But they always look so dirty. It's a bit hard to see in photos, but in person, I've repeatedly noticed the Cat and Thing 1+2 masks look visibly aged, yellowed, and darkened. There's an extent where I could believe that the darkened white on the fabric could be intentional and for theming, the Dr. Seuss books have a very iconic style of shading, so maybe the costumers are emulating that? No, in my opinion, it simply looks like they've just not replaced the heads for a very long time and it's really starting to show.
In conclusion, Seuss Landing is a land of contrasts. Definitely needs some major upgrading, but the bones are really solid and I'd love to see it reach it's full modern Universal potential.
