Better to watch some of best Hollywood movies like Gravity, Interstellar, europha report, sunshine, moon etc. Our directors are still in the L.K.G standards compared to hollywood movie plots and direction in the space movies, and our graphics looks like basic photoshop editing.
I will agree with budget limitation but there is no need of budget to develop a good story.
Recently watched The Beyond (documentary kind of) movie, there is no heavy graphics but the plot keep the audience to edge of the seat.
