Bloody ridiculous so-called music crap in the background ruining the video.

@QuantumPianist

Can't hear the music. Some guy keeps talking in the background....

@ArnfinnRian

Tragicly poorly mixed sound ruins it completely!

@WyattScott

Man, my dad was a PhD in physics from Cambridge university and worked at Cal Tech in the 70’s finding quasars as a radio astronomer, and I’m just a lowly CPA. But at age 53, I’m becoming more and more convinced my true path should have been somehow in this incredible field. It’s a real passion of mine. I just got dumbed down by my mom the librarian considerably, so the math is just light years beyond my ability unfortunately. Stephen Hawking’s books started my journey down the rabbit hole about ten years ago and these vids are treasure for me, thank you!

@pixxelwizzard

The poor sound mixing aside, this documentary was fantastic.  Thank you so much!  :)

@isminidog

Loud music and sound effects spoil the video.

@amanitamuscaria5284

Music director of this documentary should be slapped and banned from working in these.

@stewartmiller6377

Tone down the weird sound effects so the useful discussion can be heard.

@Str1derNZ

Rutherford could have split the atom with the power of the music in this video.

@johnpringle9967

Mr. Khalilli; you are by far and away the best presenter of physics knowledge in my opinion and I study a lot of it. 
However, I have done some sound recording over the years as a keyboard player and one thing I learned early on  is, ALWAYS RUN A FULL LENGTH SOUNDCHECK PLAYBACK  before sending  anything  out the door to the public!

@Idontknow819918

Music is too loud. Such wonderful content needs no music

@daleontheedge

Such a great documentary.  But can't watch it with ridiculous loud music overwhelming Jim's voice.

@fullwaverecked

Crrrazy music gets into your head with all the subtle finess of a drillbit.

@rowlandadelagun-manwomanmy892

Audio problems aside, this is an absolutely stunning video presentation! Captivating and very informative.

@audreydugan9668

I need to study this amazing video again, this time with Captions and - No sound! -  I so want to understand what he is saying - it is so Wonderful

@jmyers9853

the creators of this video got carried away with their control of sound rather than content

@albionjq

the bloody music is a real piss off at times you can hardly hear him

@mikelfunderburk5912

Background noise too loud

@nickho7113

Professor Jim  Al-Khalili,  has the unique skill of being able to break down complex physics problems  into manageable, understandable content..  His enthusiasm and willingness to want to impart knowledge is infectious. What a Brilliant educator. Many thanks for helping us understand a little better the wonders of the universe.

@fidelogos7098

Is this some sort of psychological experiment to see how much frustration a person can endure?  The parts that I can hear from Jim are golden; just wish I could hear it all.
