This is Spielberg at his most Capra-esque. This is perhaps Spielberg's least well known feature, but that is, perhaps, because it's unfortunately not all that memorable.
As far as story goes, it is, in broad terms, Ghost a year before it came out. An aerial firefighter dies saving his best friend, but has to help his friends and lover move on before he can cross over. Very sentimental fantasy type stuff, but it is Spielberg, after all.
The film is a bit too long, and the script could be more compelling, but I actually liked this film (for the most part), which is why it's close to a pass, even if it doesn't quite earn it. Maybe I'm being kind because perhaps Spielberg was just in a rut between a good film (Empire of the Sun) and a great one (Indiana Jones and the Last Crusade).
The film has okay music (though it doesn't really stand out), a decent cast with good performances, and some pretty good work where the special effects, cinematography, and execution of the aerial stuff is concerned. This film is notable for being Audrey Hepburn's last screen appearance, and, while it is nice to see her, she deserved to go out in something a tad better.
This is lesser Spielberg, but it still has it's merits. Maybe you should be like me and give it a chance. Maybe this film isn't all that bad, but just needs a little love.
