There is one nits that I remember from watching the movie.
Scientists discover a giant ring that has twenty some odd symbols on it.
In order to open the stargate, they must select seven symbols in the correct order. When our young hero first arrives, the head honchos say that they have the first six but are unable to find the seventh. Of course, our young hero figures it out and off they go. Instead, they pull in this guy and expose him to what must be a super-secret project. The only writing on the planet is those tablets, and he doesn't seem to know about them.
