Hot take - see TSL at night. Seeing it during the day is like riding RnRC or Space Mountain with the work lights on.
Nope, I'm there with you. There's certainly some cute decorative touches around the land but otherwise... eh. When a good portion of a land's general "theming" seems to come from over sized string lights and poles made to look like Tinkertoy, that might be an indication said land is short on actual substance.
Slinky looks slower than I thought it would be, especially the second half (there's barely enough momentum to get over the second launch hill). And the theming basically disappears after the second launch; there's no blocks or props or characters or anything until you get to Wheezy. The "wind up" backwards bit for the second launch is cute, though it would have been better in an enclosed tube so that that little surprise isn't spoiled as you wait in line. Plus, then you'd always see the lighting effects on the second launch; during the day they're completely invisible.
The Saucers are fine I guess, but again, riding during the day means the lighting effects lose their impact. And the stationary claw is a cop out - it should really open/close and move up and down during the ride.
The lunch counter seems woefully undersized (only 2 registers and ~25 tables?) and is going to be completely overwhelmed on all but the least busy days. The same goes for those two little merchandise carts. Losing Sweet Spells over on Sunset Blvd. to try to "make up" for this land's lack of store space only adds insult.
On the plus side, the new TS(M)M queue looks nice, and it's great to see Mr. Potato Head back!
