I don't necessarily know about "experts," and I don't know if I would go so far as use the word "hate," but there have definitely been horror Web sites that have looked down their noses at DS. Evidence for that has been well represented on the forum through the years, with many such sites having been linked to and their writings about DS lamented about.
Though Cousin_Barnabas is right that there have been more people in the general entertainment media who've looked down on DS.
And I can't speak for others, but the only reason I brought up the original series was in the broader context of DS in general and how there's definitely a pattern of how those who aren't fond of it often seem to resort to misrepresentations in regard to its various versions, so misrepresentations in connection with the Depp/DS film is, sadly, simply more of the same. Not to mention but more additions to the forum's laments through the years...
