The timing of Chaar Sahibzaade is excellent, given the extensive religious killings in the Middle-East. It is based on true events concerning advocates of religious freedom. These people courageously did whatever was necessary to restore what was wrongfully taken from the weak and oppressed. The theme is mostly about their training, and about the military forces against them. In these ways, it is a religious war movie.
It is animated, with fair-to-good foregrounds but very poor backgrounds. There is a feel of limited movement. The images of holy people are stills, since the makers considered it disrespectful to make cartoons of them (but the audio strategically keeps the flow).
The English subtitles exclude periods. The translators obviously catered to audiences of Sikhs, leaving in untranslated titles (such as Guru) and other religious and martial terms. Non-Indian audiences find it hard enough to read through the long names without all the foreign-language extras. Audience members who did not need subtitles were much more pulled. The narrated overview at the beginning aids understanding, even though it includes spoilers.
Although most NR movies are adult-oriented, this one shows the weapon attacks WITHOUT the gore or suffering. It has its battle scenes, executions, and corruption, but is hardly disturbing or offensive.
I recommend watching it, even though the art and linguistics have their problems. It expresses the need to personally battle injustice, rather than idly pray, meditate, and give in.
