I've watched this movie so many times already and in fact, I just finished watching it again while I am giving this review. This is one of my favorite Sci-Fi movies and it makes me sad to think that many negative comments were given about the film mostly saying that many scenes were unrealistic. So how come this was considered a Sci-Fi movie? The first time I watched this, I already noticed spme shortcomings actually. But I just shrugged them off as I focused more on what the movie showed like TEAMWORK, PROFESSIONALISM, AND LOVE FOR FAMILY. Considering those, I enjoyed the movie and I will watch it again and again. There were so many PERFECT PEOPLE giving their SUPER PERFECT COMMENTS as if the actors were not exerting their efforts in making the film.
