Actually, it's impossible to review this film, it's 26 films of very uneven worth.
'Cool Ass Cinema' does a great job of breaking down the individual entries there, so I'd recommending a visit to that site to gauge the merits of each individual entry.
With so many different short it could be easy to distinguish that some are easily better than others - some being good and clever, and others being extreme, unnecessary or just boring.
But, since these 26 are all packaged as one feature I find it very easy to say to avoid this sh*t.
It runs the entire gamut of horror, but the "extreme" stuff, the clear shock for the sake of extreme shock stuff made this unbearable.
I already had to listen to the f**king voiceovers on 'The Human Centipede 2: Full Sequence' as the main character slept at night; so I've used up my quotient of "putting up with shocking for the sake of it" for the year or decade or lifetime. In response to my hating that, I then found defenders of that film praise those exact same sequences for being so challenging and over the top that I didn't understand them, and that I'd dismissed them as being extreme when they were really commentaries on extreme cinema and how laypeople dismiss it.
Horror films do a great job of defending themselves when they're good, but making up sh*t to defend terrible ones is where I draw the line.
So, yes, sh*t outweighs good in this anthology - by a massive amount.
There is some good, and some very clever stuff in here that it would be a shame to miss. So if you make the mistake of watching this film then with your dvd remote in hand to skip whole chapters without a second thought. And if the entire run-time of the version you suffer through is only 20 minutes out of the film's entire 2 hour 10 minute run-time then you can count yourself lucky, you haven't really 'missed' anything by not watching the rest.
