If you judge this by the standards of a professional film, you're doing it a disservice. If you judge this to most fan films -- then it is an excellent film.
While some of the acting is stiff, and the dialogue is clumsy, there is the feeling of emotional bonds here between the characters. Some original thought went into creating "Revelations" and the plot shows it.
The special effects are very good (especially for a fan film.) Could it been tighter? Yes. Should it have been longer? Probably not. But is it worth the 47 minute download? I think so if only to see what might be coming in the future from such dedicated filmmakers and Star Wars fans.
I wouldn't underestimate the team behind "Revelations." They probably have a future in film-making.
