I think filmmaking is still a relatively new artform..
what you see popularized on TV is just hollywood trying to use gimmicks (ie: shaky everything, quick cuts, etc)
camera tricks/trends come and go, good stories stand the test of time.
I think overall what has drained the attention span of folks is convenience culture, quite a disturbing thing.... but this could veer off into philosophy territory so I'll cut it short :P
films like Aguirre, the Wrath of God, 400 Blows, Taxi Driver, Stalker.... all would be considered somewhat avant garde/arthouse and pretty far outside the conventional Hollywood techniques at the time, yet all remain classics that have withstood the test of time
same can be said for Hollywood films like Citizen Kane, Planet of the Apes, Casablanca.... a good universal story taps into the collective unconscious... this transcends just about everything...
now when you have an amazing story COMBINED with innovative techniques, well then my friend, you are sitting on the next instant classic
