Films

I loved it the first time I watched it (I was about 16), but it's not a well-structured comedy, just a series of farcical vignettes which don't reward watching it again (for me).

Missing the point a bit there... I don't think it was ever meant to be at all structured or a Comedy like others of the time (Planes Trains Automobiles, Groundhog Day, Beverly Hills Cop, Ferris Bueller's Day off etc etc...)

They all had relatively solid storylines supported by some great acting and largely great scripting. Naked Gun had an almost non-existent storyline held together almost entirely by 1 man's practically infallible comic timing, facial expressions and line deliveries, and some hilarious set pieces... not to mention great opening credits ;)

Some of the scenes from the first 2 films are just so well shot too, which makes it all that much more re-watchable.
