Query: Sober, boring and actually unrealistic space film

How can a movie with such good actors be so boring? The special effects won an Academy Award?! Theyre horrible compared to 2001, which won the year before. The movie is devoid of suspense and humor. Some people claim that this movie is very realistic, but yet Pecks character, the Chief of Manned Space talks to the Apollo craft more than CAPCOM does. And if the Russians could change orbits, why didnt it earlier? Also, NASA tests their astronauts extensively for long-duration missions like Space Station missions, how did they miss that Hackman is suspect-able to space madness? Tip to Hollywood writers: Dont write a fictional astronaut movie. Movies like that (Marooned, Altman's Countdown [not his fault, WB took 30 minutes out of it, would love to see that one day] and Capricorn One) stink. It needs to be based on reality (The Right Stuff, Apollo 13, From The Earth to the Moon).
