Maybe. Despite the number of times I've heard about CRT and how bad it is, and how good it is, I still don't have the foggiest idea what it is. One time, I tried to look it up on the internet. Signal to noise was so bad, I still don't know. I've written off the possibility of ever knowing what it is or understanding anyone who's talking about it.
As with any field, there's a number of detractors and charlatans. With CRT in the political spotlight, I completely understand how it becomes a mess to make heads-or-tails of.
Broadly speaking, it's the study of how law and media impacts society's view and treatment of others through the lens of race.
As for my opinion on it:
I generally support it because it advocates for another mechanism to study the impact of law.
I think most legislation should be regularly studied for impact, effectiveness, and fairness. For example, stimulus bills ought to be reviewed for economic impact, regulation ought to be reviewed for effectiveness/relevance, laws with social impact ought to be reviewed to ensure it doesn't harm the people.
A number of scholars seem to adopt a blameless mentality to figure out how laws (even unintentionally) have negative impact, and use that to propose solutions. I admire this approach to legislative critique.
While I think a few ideas some scholars advocate for are infeasible to implement, the broader field has a lot of merit.
