It is great! Worth it? Idk.
The content is the most concise and well laid out educational video for NLHE I have come across. Negreanu is a great teacher but has lots of free content on his YT channel. I think you could easily find all that is covered I his Masterclass on the internet but it would require sifting through lots of articles and hand breakdowns.
To learn basic to intermediate strategy and hear it from the engaging and entertaining perspective of one of the most infamous poker pros has value. If you ask me $90 for the one class is too much. I got the deal where you get two all access passes for $180. $90 each for all classes for a year has been a great value and I have enjoyed not only poker content but chess, cooking etc..
If you have read several books, paid for GTO solvers, use equilab/flopzilla for off felt training this is probably too rudementry.
For a beginner it is an ideal format and pushes into more advanced strategy. I like it because it is laid out in such a matter that is solidifies the knowledge I have. In poker it is easy to lose the big picture as it is so situational. Daniel ties everything together well.
Hope this helps
