It’s funny how people still ask which one is better, Interstellar or Project Hail Mary, because the answer is clear : they are brothers. If Interstellar is a first son -a tough, serious and responsible child-, then Project Hail Mary is the second son -a fun, easy going but still responsible. I really enjoyed the movie from the very beginning to end. Grace and Rocky really make us laugh, feel warm, cry and feel content. Ian happy Grace and Rocky together, statement.
