Just as a counterpoint, I loved the trooper storyline, even after playing through two other classes (Jedi Knight and Sith Warrior).
To put it bluntly, no, the Trooper story is not boring. If anything, I think it's one of the best pieces of star wars military fiction outside of the X-Wing Novels or the Heir to the Empire series. All the squadmates are varied and interesting, the story progresses logically and yet still holds many surprises. Finally, as a trooper, you get a very real feeling that you're the one who's saving the Republic while the Jedi are busy saving the Galaxy.
although the beginning planet storyline is so stupid lol
