Unless you have the correct size large screen display and watching it from an average distance, and a really good surround sound system, there's nothing like the big screen scale and sound in an excellent movie auditorium. Unfortunately, those theaters start from mediocre, poor projection and damaged screens, to audio systems that should be relegated to the trash barrel. You are also, in the end, at the mercy of the projectionist, much like you were at the mercy of the janitor at school for heating and cooling!
There are many films I enjoyed when I was very young that do not bear up to my standards today, but, of course, some guilty pleasures. I enjoy using NetFlix mostly for independent and foreign gems I've forgotten or somehow missed. I can usually rely on the user ratings and reviews there (those films attract the more discerning viewers), but I also refer to my favorite critics if I don't recognize the title. On many films, the user reviews are going to be practically worthless just as Phoenix pointed out -- there have always been films aimed at a pin-headed teeny-bopper audience and I'm afraid "The Lost Boys" was one of them. It has some redeeming features but a filmmaker can't please everyone all the time (to paraphrase Lincoln). Hollywood, and even other churners of movie entertainment like Bollywood, have got to keep the box office going up and not down. They can make those little gems. You can't bank of all independents or some foreign films that are made for the love of filmmaking, either. Many of those are real clunkers, but maybe more worth watching that the intended blockbusters.
I did figure out that on-line, it takes about five to ten minutes to at least scan critics and user reviews and see the rating. It's time well spent, considering you are going to give up ninety minutes to as much as four hours at the hand of a sometimes a sincere and sometimes a hack filmmaker.
