I went to see Gnomeo and Juliett today - it's alright seems to be sponsored by Elton John, but is inoffensive, mindless entertainment.
However, the mother next to me in the cinema, had two boys guess aged around 4 and 6, and proceeded to tell the boys how the film related to the Shakespeare version of Romeo & Juliet.
AIBU to think:
a) shut up you are in a cinema don't talk unless necessary, and your kids are sat there quietly watching
b) let them enjoy the film, the film has a very very loose basis on the original, about the title is similar and then all other similarities stop!
