Freud is described as a pseudoscientist now, by some, though I disagree. Many of his concepts are now part of popular talk, and we don't even notice it. Like when we talk about the sub/unconscious, for instance. And we all know the unconscious exists, cos of how we may be unable to remember something now, but we remember it later, so it's stored in there somewhere, but we can't always access it. Or defense mechanisms, or Freudian slips ... there's a big list of valid contributions he made, and he also popularized the field. Dunno why some feel the need to denigrate him.
