I haven't had much success with Japanese film (as in programmes with actors) as learning material, but there are often differences from one person to another in what works best.
Eyeing overflowing shelves of anime series and a burgeoning manga collection in the lounge room.... Hmmm: waste of time, certainly
, waste of money, indubitibly
, worth all of it

Problems associated with watching Japanese programmes:
characters often do not speak standard.
Spent weeks trying to track something with a like sound to "ushi" meaning tasty. Then I found out that Iwataken dialect sounds "o" as "uu" and tends to suppress "i" after "o." oishii it was. (I have never forgotten the Japanese word for cow.)
Likewise "a" can sound as the "ar" of "war" - By the time I encountered eddoben for the first time, I understood just enough Japanese to not be thrown by "desh kar," (desu ka) but I still tripped over the "war" type sound for "ha," mistaking it for the elegant "wo."
Japanese is a rapid fire language. Recording pieces of soundtrack that are of interest and then slowing them down to 15% speed using a program that doesn't distort the sounds in the process, you actually get to hear all the syllables instead of just a few. That is an annoyingly time consuming process but well worth the effort (and extra money.)
After a time, I took up buying manga and anime for the same series. That way I get to actually examine forms and grammar while listening to the sounds of what I am reading. Problem: Anime often does not use the associated Manga as a script, so there are variations. For Ichigo 100% there is not enough confluence to make the exercise worthwhile. However, DearS almost can be said to use the Manga as the script.
Finding a nice online Japanese bookshop for mail order is a must - second hand manga can be had for around $5 - $8 including postage.
Theme songs make for a good jump off point in study. Aa Megamisama, Nana (!), Mahoromatic, Full Metal Panic, Infinite Ryvius, and songs within Nadeshiko (the contest for captain's post, in particular Ruri's song.) are worth learning. Songs increase vocabulary word count in double quick time. Downside: grammatical constructs are often unlike spoken Japanese. (same occurs in English.)
For learning Japanese from anime, look for target age groups around 10 - 12. Language tends to use simpler grammar, more clearly enunciated speech, closer to Standard pronunciation than anime targetting older ages. There are a surprising number of very interesting stories, and stories that are interesting in their own right don't put you to sleep while you are trying to study. s.
