My wife and I watched most of it and, although it was well acted and had a great cast, we found it meandering, pointless, self-indulgent and boring. Eventually we turned it off and read instead. Felt like an absolute waste of an hour. I won't bother watching the rest.
Oh, and the Bruce Lee segment just seemed like a needless insult to the man.
Fair enough I can respect that opinion, the last hour does tie it together but I think I enjoyed the 60's atmosphere and look as much as anything, plus already knowing the background story in detail.
As for Bruce Lee, seems Tarantino may have based that on an alleged incident of stuntman and early MMA pioneer Gene LeBell being bought in to out grapple Bruce after Bruce was rough striking with some stuntmen, that may or may not be true, definitely not as the movie portrayed it, and certainly not as confirmed as Gene LeBell doing much the same to Steven Segal many years later.
