'bromwell high is a cartoon comedy . it ran at the same time as some other programs about school life  such as  teachers  . my   years in the teaching profession lead me to believe that bromwell high  s satire is much closer to reality than is  teachers  . the scramble to survive financially  the insightful students who can see right through their pathetic teachers  pomp  the pettiness of the whole situation  all remind me of the schools i knew and their students . when i saw the episode in which a student repeatedly tried to burn down the school  i immediately recalled . . . . . . . . . at . . . . . . . . . . high . a classic line inspector i  m here to sack one of your teachers . student welcome to bromwell high . i expect that many adults of my age think that bromwell high is far fetched . what a pity that it isn  t   '

'i couldn  t hold back the tears when i watched this beautiful documentary . it was heart  breaking  disturbing  and inspiring all in one . i recommend this documentary to anyone seeking something that will make them think about what they are doing with their own lives . or simply  something that will make you think . you watch as john lives through the last couple months of his life . you watch as he goes through his days with a positive attitude . at one point you begin to see that he is truly an amazing individual . you begin to understand that he has something to teach all of us . his life and struggles will make you cry  laugh  and find that life  s a lot easier to live if you just take it one day at a time .
