The Guardian (2006)

The United States Coast Guard finally gets its chance to shine in this film about superstar rescue swimmer Kevin Costner who is temporarily given an instructorship at the Aviation Survival Technician training school after his entire crew dies during a rescue. The training sequences where Costner butts heads with champion swimmer Ashton Kutcher are really good. Kutcher surprisingly holds his own against the veteran Costner. But then the film just refuses to end and each new potential ending just muddies whatever message the film was trying to sell. The film could have probably excised either of the love interests and a handful of other characters and it would have been stronger for it.
