Look, there's a lot of great reviews here and I agree with all the ones that are great giving him four stars or above.
This film had me hooked in on the beginning. As stated already the attention to detail on the sets was amazing. Listen this is the back story of a film that was being made. I think what's happening here is too many people are comparing it to the actual film story.
Make no mistake if you want to get it take back on a great film, grab your popcorn glass of wine sit back and enjoy this series.
The acting was great the storyline follows fairly close to the original truth. This is what makes a great series or film. Kudos to the cast and series writers.
NOTE: oh yeah, there's a reason why rotten tomatoes has the word "rotten" in front of it.
