I assume that with “Did not work” you mean that the plugin doesn’t work in the block editor (“Gutenberg”). If this is the case, let me tell you the following:
The block editor was introduced in WordPress 5.0, but as you can see from the overview page of the plugin (https://wordpress.org/plugins/slick-slider/), it was only tested with WordPress 4.8. So you’re basically criticizing this plugin for not working, although it doesn’t even pretend to work with current WordPress systems.
If, for whatever reason, you hadn’t found the above link, you should at least have written your own support post before submitting a review (that would have justified the effort of creating a profile better than this review). As you can see from the overview of the support threads (https://wordpress.org/support/plugin/slick-slider/), all but the link mentioned are marked as solved.
So the next time you want to write a negative review, think about this before you do.
