Movie Theatre:
People coughing, people sniffling, people talking, people smelling, people texting, people crunching popcorn, people crinkling food wrappers, people slurping drinks, people's germs, shared restrooms, people's leftover trash, people's heads obstructing the view of the movie screen, people getting up and walking around.
Food and drink is expensive.
Can't pause. Can't rewind. Can't stop and play at a later time. Can't rewatch without paying again. Can't enable subtitles. Can't adjust the volume. Can't adjust the screen. Can't change seating point of view, or screen angle. Can't cuddle with a loved one.
Home Theatre:
None of the above problems.
