people don't get this movie
i've seen "you just don't get it!" thrown around several times on imdb, almost universally inaccurately (example: "the unsimulated sex in short bus offends me!" "you just didn't get the movie").
for once, however, i think this claim seems to fit. i think art-movie lovers seem to come to this movie expecting some life-changing moral, while (what to call them?) "people who don't like art movies" (i guess) get upset about the production values and rambling dialogue.
...and then people make a ton of threads about "i walked out of this movie after 10 minutes and it's the worst movie ever!"
really though, it's a rambling study of real life, whose crafted events and plot turns are all the more interesting for how they're woven into the unconventionally paced/acted narrative. if you're not interested in new structure (that might not actually work out to be esthetically pleasing or get at anything profound) nor in realistic character study simply for the sake of it, you probably won't like this movie. ...but saying "worst movie ever" just indicates that you don't get that last sentence i just wrote.
i fully understand people not liking this movie. personally, i watch it much better while doing something else. at the same time, the vitriol with which people criticize it is really off-base... "i paid money and then i was bored!" is like saying "i only like modern art, and i paid money to enter this ancient art museum AND I DIDN'T LIKE IT! COME ON I PAID MONEY!"
chances are i wouldn't like 2fast2furious. however, if i paid to see it, then walked out like "WTF this movie is more about cars than anything else!!?!?" what would that mean? it would mean that i just didn't get it.
