After visiting the land two times and having experienced everything from the Land as it transforms from day to night, the rides, food and the (limited) entertainment, here's my comprehensive review of the land.
Land theming/atmosphere
The land is very lush, colorful and vibrant at night with a nice view of the DHS fireworks to boot. I'm not sure how much the land succeeds on making us feel like toys as much as just being surrounded by over-sized toys. Either way, the land looks good and the use of the backyard fence to block out views of the large parking structure just beyond it works well. The land does have some downfalls though. The lack of any indoor spaces is an issue and the back half of Slinky Dog leaves much to be desired thematically (your main view is of a Back of House support building), but this isn't something that most of you didn't already know.
Unlike say, Pandora, which to me feels dead most of the time (dead in the sense that there's no kinetic energy), TSL delivers two rides that really make the land feel alive and, when the Green Army Men are performing, that adds a little extra to the land as well.
Rides
Alien Swirling Saucers - Posted wait time 45 minutes, waited 30. A clone of the Mater's Junkyard Jamboree ride system, this ride is a fun addition to the park, but definitely not worth waiting that long for. 30 minute wait was tolerable and went by quickly as we were constantly moving, but i'd even go as far as to say 20 minutes maximum is really the most one should wait for it once you've experienced it once (that was the only reason I got in at a 45 minute line - just wanted to do it once). I will note that the queue did have fans, but they weren't blowing hard enough to really make a difference. I don't even want to imagine what it feels like during the heat of the day.
Slinky Dog Dash - Rode the ride twice. Both time the wait time was posted at 145 minutes as I said in the general discussion thread. I waited 35 minutes the first ride and 27 minutes the second time. My sister, 10 y/o, really enjoyed the ride and was the reason we went a second time. As for my personal opinion, maybe I just had low expectations, but the ride did surprise me a bit. It goes faster than it looks and it has a certain kick to it in parts that's unsuspecting.
However, it did not feel longer than SDMT like many have said. Wheezy at the end of the ride is a nice touch. Overall it's a fun coaster and provides an alternative for those not willing/not tall enough to ride RNRC. Slinky also had fans in it's queue and once again, none of theme helped actually make it feel cooler, save for portable fans right at the load platform that were blasting.
Toy Story Mania - Obviously not a new ride, but it is part of the land. I did FP on the ride today and saw the "theming" or lack-thereof upon the entry into the FP queue. Certainly stands out in a land that - for the most part - tries it's best to immerse you into Andy's backyard and that whole story. As I understand it, the building that we enter is themed like a cardboard box that Andy would've used I guess (this is carried out throughout many parts of the land), but it feels too bland and the propped open push-doors make it feel temporary.
Anyway, with DCA's version reopening not long ago, it would've been nice to at least get some new games with the land opening.
Food
Ate at Woody's Lunch box tonight. I got the "Totchos" and also was able to sample both items on the kids menu as well (they messed up the order so I got one of the meals free). The Totchos portion size is pretty decent. I thought that all of the different flavors blended together very well and the dish was filling. I also got the three cheese blend grilled cheese. Overall it's fine, but I thought it was a bit too cheesy.
I waited probably a solid 25 minutes for food and there's very little table space to actually sit down and eat. Luckily that wasn't an issue for me, but i'm sure it is around lunch time. One of the Cast Members working at Woody's Lunch Box mentioned that on opening day, they had 5 hour long lines just to get food out of that little shack.
Entertainment
The only land entertainment is two separate shows that the Green Army Men perform. I've yet to properly see either.
Overall
The land adds fun family-oriented experiences to DHS, however, given the allotment of land used, you can't help but feel like there could've been some better choices made to put the land to use at it's fullest potential. One more ride would've really helped out and it feels like they missed out on a blatant opportunity to have a Character Dining experience that likely would've been incredibly popular. The land shines at night as the area lights up, something that I think the land does better than Pandora - a land that advertised itself on coming to see it at night. The land also provides a unique view of the fireworks, as the firework launchpad is right behind the land and across the street.
As
@Brian G. put it, the land is "Fine". It's nothing fancy, nothing i'd go planning trips around. It looks good and the rides are fun. There's always going to be that looming thought of what they could've done here, however.
