The OP of this topic seems to have already pre-judged the game and found it lacking, and is only looking for an excuse to condemn it. The writer of that article claims to be a D&D enthusiast for 40 years, yet is unfamiliar with the 5e rules about how actions, bonus actions, and movement works.
He also complains about fight with the mind-controlled fishermen being hard to avoid, but...
you can take a ranged character, sneak around the edge and use the ranged attack to finish off the Mind Flayer. Attack averted.
I did that the first time I encountered that, without bothering to try talking to them first.
