Deadpool is the BBFC's most complained about film of 2016 - BBC News
Also mentioned as being on the list are 'Suicide Squad', 'Miss Peregrine's Home for Peculiar Children', 'Jason Bourne', 'Sausage Party' and 'Batman V Superman: Dawn of Justice'
However, it seems that none of the complaints were about how bad 'Suicide Squad' and 'Batman V Superman: Dawn of Justice' were!!!
