Agreed. They use the word "problematic". Any time I see someone using that word, I close the tab instantly to avoid the brain damage that would result from me reading the rest of the piece. The word is meaningless and cowardly. Say what you think. Quit tap dancing around the conversation.
And by not at least naming one of the problems, the author is being cowardly and/or lazy. It's like describing a reviewed item as "good". It conveys no information other than "I like it". The word "problematic" does the same thing here. It signals that the author doesn't like something but doesn't tell us anything about why. In other words, it's fucking useless.
