All I can say is that Return to Monkey Island was a big disappointment. Just because newer generations might find it cute or even good relatively to the huge and boring trash people play these days, it doesn't mean that it is not a let down for people fortunate enough to game in the 80s and 90s. The first 3 adventures were legendary and iconic; it is sad that the original team never found out about their impact for years. And it is even more unfortunate that they are now basing their design decisions on feedback from NG gamers who won't even care or remember after a couple of months.
I didn't fancy the NG graphics, I didn't like the UI, I found the music meh but it was the mediocre plot, the voices (with few exceptions), the uninspiring (new and old) characters and the lack of development, the unfunny dialogues, the overdone nostalgia and need to explain everything, the evident fear not to insult any social group and the overcommitment to make everything (too) "balanced" demographically, the empty places/islands/screens and the lack of interaction there, the mediocre cut scenes, etc that I hated most.
LeChuck could be done much better, Elaine was always dependable, smart, witty, and understanding in the series but _too_ understanding and boringly cute here, Wally felt like a robot, Carla was too busy, Murray was underused, Stan, Otis and Voodoo Lady had their moments, etc. The game didn't make me grow attached to or even care about most of the newly introduced characters.
There were a couple of good ideas and moments, some good puzzles, some level of non-linearity but there were even more missed opportunities.
