Amethyst's Shiny Pebbles

My husband and I are considering signing up for streaming Netflix.  I've poked a little bit at their selections and am impressed, but slightly skeptical.  While looking for a different film (which they don't seem to have), _The Pirates! Band of Misfits_ came up... which is still playing at my local theater, having only opened a month ago.

I note that there isn't any indication as to _when_ it will be available on Netflix, nor yet whether it'll be available as a stream, disc, or both.  WTH? 

How far can I trust the not-yet-a-member browsing feature?  What's your experience with streaming Netflix and its catalog?
