The revenge sequences are nothing.
The only nasty bit to make you wince is the bath sequence,but even then its not explicit.
The other revenge scenes are tame compared to stuff allowed today.
To those who think its nothing,remember ,unless you are watching an import version then the whole thing is cut to shreRAB and a waste of time.
Natural Born Killers was also cut.
Although the unrated uncut version came out on R1 I'm not sure if the R2 is uncut or whether its still the cinema version.
Chainsaw Massacre has never been cut in the UK.
It had a very limited cinema release in 1974,then a video release in the early 80's which was deleted (not banned) and eventually got re-released in 1999/2000.
All of these versions were uncut.
The BBFC actually rejected it outright in 1974 but Westminster Council overruled them(as they can still do with cinema releases,but not dvd).
Various distributors discussed releasing it in the 90's with the BBFC,but thanks to James Ferman it was never officially put in for certification as he told them it was pointless.
This was also the case with films like The Exorcist,Straw Dogs,Evil Dead and others.
No sooner had James Ferman been kicked out of the BBFC than most of these famous films were speedily certificated
and put on dvd.
JF obsession with chainsticks also meant that Enter The Dragon was finally released uncut to dvd once he was gone.
Some films he kept away like Death Wish did get a release,but were cut and DW has only now been finally passed uncut,although its 1974 cinema release was uncut
