This question is receiving a lot of close votes (3 at of this moment), but I am not sure I understand why. Of course it is not very well written, but I think it can be turned into a valuable resource. Can someone explain to me why would someone vote to close instead of suggesting an edit?
My reason for closing such a question is perfectly encapsulated in one of the standard motivation:
Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise.
There are tons of methods, websites, apps, guidebooks, schools etc. to learn Italian, from browsing an old-fashioned grammar to come to Italy and live here, learning just by having to. In fact, there are tons of categories of ways to learn (courses, full immersion, self-teaching, programs).
We couldn't even hope to list a significant fraction of them (not even, say, for a single category), much less so asses their relative merits and faults. What would happen, in the best case, is that a handful of people would tell about their own favourite or most loathed course, website or book, which is exactly how not to tackle seriously (let me say, scientifically) a question.
In movies.SE one would receive a cold response if, say, they asked to be suggested a good James Bond movie, but at least it would be quite feasible to list all of them. Here somebody is asking about a good movie.
"List" and "advice" questions are frowned on at most SE sites because they are too "personal," that is, they require a great deal of personal, as opposed to general, knowledge to answer.
Italian SE allows less leeway in these matters than some of the other sites I've been on.
