Finally got around to playing this, was not disappointed. Luigi is back with another entry in his unique franchise of kid friendly scares and humor.
The game is arguably the most gorgeous game on the switch and somehow ran smooth the entire time until before the final boss fight. The music is good, the gameplay is fun, and the atmosphere is incredible what more could you want.
Actually I can answer that, because the game suffers with its characters, level design, and controls. Compared to the first game the bosses in this game are completely forgettable outside of the cat, director, and hotel manager, the controls are frustrating at times with how the plunger and flashlight features just doesn't hit their target, the level design is really hit or miss with fixed cameras making some sections rage inducing, and for me Luigi's voice sounds extremely off but as I haven't played many Mario games since the GameCube era this could just be his new voice and I'm not aware of it so I won't hold it against them.
I still think this is a really fun game and highly recommend it if you want a fun time, and it has coop making it a fun adventure to play with your family or friends!
I didn't touch the multiplayer portion of this game so I'm not counting that in my score.

On Christmas of 2015, I got a present that changed my life. I got my first ever videogame console; a 3DS XL, and Luigi's Mansion 2: Dark Moon. I played the game and loved it, it just clicked for me. It helped me make friends, develop as a person, it was something I could always fall back on when feeling bad.

When booting up my switch in September of 2018, I saw a notification in the news section on the left "Luigis Mansion 3 (working title)" had been revealed. I screamed so loudly in excitement that I lost my voice for 3 days. The reveal trailer was pretty short, but it showed enough to get me extremely excited. Luigi was back, and he looked better than ever! In the following year I obsessively stalked nintendo's youtube channel eager for more news about this game, and when they dropped an overview trailer during E3, my hype grew even more! This was my most anticipated game of all tame. I was lucky enough to go to Gamescom in Germany in August of 2019. It was an experience I'll never forget, Huge areas and tons of people that loved games, and were just as excited as I was. When me and the friend that invited me finally got to the Nintendo section, there it was, Luigi's Mansion 3!!! I was so excited, I was prepared to spend the entire rest of the day in line to try it out. But my friend and his dad didn't want to, and I was still too young to be out on my own, especially in a country whose language I don't even speak. So they didn't let me play. I was fuming. When halloween finally rolled around, I was stoked. Me and my best friend who I always used to play Dark Moon with held a small halloween party. I was dressed as Luigi with the Poltergust 5000, and he was Mario in a painting. We went trick or treating, and got a load of candy. Then we went back to my house, and started playing. We played all night long, and had already finished the game the next morning, but we'll never forget this magical experience. I truly think there will be no game that can ever get me as hyped as this one did, and the memories I have with it make this one of my all-time favorites.

Safe to say, I might be a tiny bit biased.

Sure, this game has less ghost than the two games before it.
Sure, the atmosphere isn't as good as the first game.
Sure, the plot is kinda stupid.
But the personality OOZES from this game.
The mechanics and gameplay is the best yet.
The abolishment of the mission structure was a really good choice.
The animations are buttery smooth.
The Hotel is filled with interesting puzzles and varied locales.
The scarescraper is better than ever.
The party mode is really fun.
The visuals literally look like a PIXAR MOVIE.

You should give this game a shot, it's really good.

I don't really know why these games receive the praise they do.

My brief history with LM as a series:

I love Luigi as a character. Always have. He was always my choice as a kid in every Mario game. I was super excited when Luigi's Mansion 1 came out; he was finally getting his own game! Played it at launch and was very disappointed. It's boring.

Since then I've avoided the series, but this year I decided to finally try out 3. It received enough praise at this point that I was willing to give it another chance.

Nope. It's still pretty boring. I like the presentation. It's a pretty game, and the way Luigi emotes is great. The music adds to the silly/spooky vibe - it's great too.

Everything else, though - meh. It just felt like a chore to scour each room and suck up a bunch of coins that felt meaningless. Puzzles are generally the low point of every game I play, and this game is essentially nothing but puzzles.

It's just not for me. There's little to no challenge and there wasn't anything pulling me forward or encouraging me to continue exploring. It also began to feel repetitive very early on. After 7 hours or so, I'm out.

It's not as good as the first game, but LM3 is a fun experience. The game is much, much better as a couch co-op game than it is as a single player game. It loses some of the charm of the first game, and at times I deeply miss the charm of the first. Little actions like using the Gameboy as a camera and seeing the ghost profiles in your little ghost pokedex after you catch them.

Still LM3 is great fun and Gooigi controls just as well as Luigi. I'm actually surprised the game even has a single player design because co-op felt much much much more natural
