Yes. I do realize that this film has indeed lost a considerable amount of its venom, clout, and vicious bite since its initial release back in 1966, but, all the same, I certainly don't think that it was really all that good, anyway.
IMO - A film whose sole focus is to zero in on some seriously demented marital dysfunction certainly gets to be a mighty big bore, real fast. If you don't take this film's stinking bull at face value, then having to endure watching the blowzy, lard-assed Elizabeth Taylor verbally duking it out with the loud, obnoxious Richard Burton can quickly become quite humorous, almost cartoonish in nature.
Back in its day, this film was considered ground-breaking (and, I guess, it was) for its high level of profanity and sexual implications. This was the first film to use the word "bugger", and the phrase "screw you" in its dialogue. And it was also the first to be given the MPAA tag - "No one under 18 will be admitted unless accompanied by his parent."
