This movie is generally not highly regarded. Criticisms refer to the lack of plot or "aimlessness" and draw unfavourable comparisons with the song.
It is hardly ever appropriate to criticise a film by comparing it with the source from which it is derived. The film is a work in its own right, and it is no criticism to say that it is not like something else. There is no reason why a comic song should not be used as the basis for a tragic movie. The only such comparison that has any validity is one which uses the source work as a basis for demonstrating how a weakness in the derived work could have been avoided; or conversely, one which contrasts a virtue in the derived work with a corresponding deficiency in the source work.
On its own terms, "Alice's Restaurant" succeeds very well as a movie. The song on which it is based does no more than provide a sequence of events around which the movie is constructed. It is not a narrative; it is a portrait of a particular time and a particular section of American society. It meanders, but it is never tedious; there is always something interesting to see on the screen. It demonstrates how that section of society, or the representatives of it with whom the film is concerned, although rejecting many of the rules by which American society has historically been governed, nevertheless accepts that society's basic values and cannot avoid the consequences of the rejection of some of the rules. It is not a great movie, but it is a very good one.
I rate it as about 7.5 out of 10. The film that I find most similar to it is the French film "Round Midnight"; not because of its subject-matter, but because of its dreamy, unhurried mood.
