Hate-watching (a term I had never heard of before kirk55555 had brought it up) implies that you watch something that you are determined to hate, it implies that you have decided, beforehand, that you're going to hate something. The people who do this are self-proclaimed 'Über-Trekkies that stand by Gene's vision', but preconceptions and prejudice go against everything Gene ever stood for. I know we should all be open and kind to one another here, and I believe in that and I will live by that, but man: hating something you haven't seen yet is, as Spock would say, illogical. So I really hope that even the greatest pessimist will watch the pilot with an open mind and make judgment after actually seeing it.
Come to think of it, is there a thing as 'hate-eating'; someone who goes to a restaurant, orders something he has never eaten before, proclaims beforehand 'I am hating this!' and THEN starts eating. Wouldn't the people around him ask him: why did he order something he hate? And after he says 'I've never tried this before', wouldn't they ask back: but shouldn't you try it first before claiming you hate it?' If that person would then say 'no, 'cause it's got these green things on it and it's got this weird shape, so I'm hating this!' Then (if they're patient enough) the people would ask: 'But isn't about the taste and the way it's prepared: the flavours, the aroma, the combination of spices? You should really try it!' The guy then replies with: 'No, 'cause these green things and the shape are more then enough information for me, I've made up my mind: I HATE this!' He then takes a bite, walks away and leaves... only to come back the next week and repeat this cycle. Sounds crazy?
