Whats your opinion about Gutenberg ?

WordPress Core Team is getting ready for inclusion of Gutenberg, As WP developer I am getting familiar with it and for starters I installed Gutenberg plugin on local environment to play with it, while installing I noticed it has 2.7 stars which very low for the plugin which going to be part of “Core”.

There are so many negative reviews about it, most of them are added recently look like people are really mad about it.

I am not totally familiar with Gutenberg to judge it but want to know why people hate it so much.

please let me know whats your view about Gutenberg
