Severance and Shaun of the Dead...
The DVD box said that this falls in the same vein as these two (well a publicity-whoring horror website - which I won't name - said so), but Botched feels really half-assed, whereas the other two were very well done. The filmmakers associated with this movie didn't really put a whole lot of work into the writing or comedy (a few cheap chuckles) so if you don't smoke weed and are over 20 I just don't see how this could strike anyone as a "laugh fest". The horror part (which is FAR too sparse) is good... but needed much more of it.
If they would've gone a little more with the horror and less with the unfunny humor - and added a stronger connecting plot - I think it could've been a decent watch. But I have to say this one is painfully average... not the worst I've seen and certainly nowhere near the best.
