Not according to my friends and family who are not big Tolkien readers (some are GoT fans too) - they are really enjoying the slow build and world building. Lots of recent streaming shows (especially multi season ones) take at least half a season to get going. Often the second season is really where the story starts (when viewers are familiar with the characters and the locations etc). I do think that a lot of the push back is from people for whom this isn’t ’head canon’. People who don’t like fantasy or epic storytelling aren’t going to like the show no matter what (my mother and sister would be in that camp).Not all. There are non-book-readers who are clearly put off by the "Karen&Mary Sue" Galadriel and do finds the overall story boring - which is the most common accusation I do hear. My husband - who is not a Tolkien fan and has not read the books - fell asleep during the 3rd episode. And that seems to occur quite often - at least it gets reported often.
