I am not forcing you to watch movies you are not enjoying to the end.
But if you don't finish it, you forfeit the right to give it judgement, or at least, you opinion holds no water.
I mean would you trust any film critic who doesn't finish the movie? Would you trust a food critic when he only ate the starter and not the main? Can you judge a country because you only been to the airport?
Finish the movie, then I will then entertain your opinion on a movie, any movie.
Don't finish it, you shouldn't and can't judge it's entirety.
The MOST you can say is you turned it off and it wasn't for you. Your verdict shouldn't be on the entire film, your verdict can only be for what you have seen, as opposed to what you haven't seen.
I think that's more than fair.
If you had judge movies on the 15min mark:-
The Green Room - the band hasn't even been on stage yet.
The Rock - Nic Cage is still back at home with his wife.
The Revenant - the bear scene hasn't happened yet.
Antman - He hasn't even got his suit.
The Groundhog Day - the loop hasn't even begun, it's still the first day.
Taken - his daughter hasn't been taken yet.
Ironman - the weapon demo in the desert hasn't even happened yet.
Home Alone - Kevin's family hasn't even left the house for holiday.
Ferris Buellers Day Off - His friends are still in class.
Die Hard - Nothing has begun, not even seen a gun yet.
Back to the Future - You haven't even seen Doc Brown yet. The car park scene hasn't happened.
Splash - Darryl Hannah hasn't appeared on screen yet.
Mulholland Drive - Naomi's character hasn't even shown up.
Jerry Maguire - He hasn't quit.
Gone Girl - Rosamund Pike's character is still on screen, she hasn't "gone" yet.
See what I mean? If you had stopped these films at the 15min mark, you would have missed the entire point of the movie. Taken? Taken what?! He hasn't even said "I have a special set of skills", all you have seen thus far his him having lunch with his ex-wife and daughter.
So yes, feel free to stop movies after 15mins if you don't enjoy it but that cannot be the true reflection of the whole movie and you should not call judgement on it either.
It's beyond obvious that I will not have seen the story play out, as I didn't finish it.
However I'm giving my verdict on the tone, on the quality, on the intelligence of the movie - and I saw enough in the first 15 mins to know that it was a very cliched, lowest-common-denominator targeted, lazy film.
I am happy to pass judgement on this film based on what I saw. I was good enough to let the reader know I'd bailed on the movie after 10-15 mins (exact time unknown).
It's up the reader to decide if that's a fair basis for making a judgement or not.
I for my part will continue to pass judgement on awful movies despite not watching them to the end. It's up to you to decide if you care what I think or not.
No, I'm not a professional critic - I'm not getting
paid to watch awful films to the final credits, so I'm damned well
not going to! Yet I have complete confidence -
complete confidence - in my ability to spot a terrible film from the first 1/4 hour.
I do not believe this is some mystical power that I alone posses - I believe the vast majority of us will have made a judgement call to switch something over/off after a similar timeframe.
And I believe most (if not all) of us would then have said to someone we know, "Suchandsuch is an awful film - I walked out/turned it off". Does that equate to professional criticism? No, of course not. But is this thread reserved exclusively for Mark Kermode and chums? Nope.
e: Just to add to that - if we only review films that we liked enough to watch to the end, then we are skewing the review scores. We will only have people giving ratings for films they liked; films that were so awful they got turned off/walked out on - nobody will be able to review them!
How is this good for anyone? To skew the results so you only get positive scores, or only hear from people masochistic enough to watch something they hate all the way to the end? Some of us have better things to do!
