The movie tells a good story rather than just to complete the two episodes of Star Wars series, and this is a real Suicide Squad who has known they would die to finish their mission but they still devote themselves to it because of their hope. It is sort of routinized but you would still be inspired.
The ending part is not routinized or stereotyped at all (spoiler alert ahead): every hero truly devote their life to the great mission, which reminds the audience that wars are wars and there are sacrifices, not some funny games at all. The ending part deepens the tragic atmosphere and makes the audience feel the power inside.
Again, like other Star Wars movies, this episode has a cute robot called K-2SO.
