well, different cohorts are by their very nature, different. 
has there been a change in the catchment demographic/ area for any reason?
you do know that lots of mners are governors, right? and that in an awful lot of cases, the cofg is an an ex teacher or ht that still wishes to use their expertise and many years of experience for the benefit of students, right? and that anyone that volunteer to be a governor, but that you are required to complete an application process and attend training courses?
the tone of your op was singularly dismissive of all these facts and might not be the best way to engage with what you feel is a real problem.
did you listen past the 'blaming the kids' bit? what was the meat of this particular sandwich? are there a higher proportion of unfunded sn students in this cohort? have teaching methods been changed in the last year?
you know the role of the governing body right? the best way to get answers and positively alter outcome is to put yourself up for nomination as a governor. use your own experience of education to be a force for the good - particularly if you are unhappy with the current status quo. (if you have it experience and are willing to volunteer to runa school website, i bet the HT will bite your arm off - with a poor ofsted, they are probably looking at encouraging their staff to concentrate on educational outcomes. that's not to say that parent liaison and pr isn't important, it is, but it might not be what ofsted criticised the most.)
i presume you have a copy of the ofsted report and the detail as to which areas were not up to scratch. how does the governing body intend to ensure that the ht and teaching staff deal with the issues? does teh school have a school improvement plan? have you seen a copy of their 3 year plan? an excellence plan? who is their SIP? what does the SIP say? was he/ she at the meeting?
lots of things to mull over other than the cofg was negative, i think.
