The Movie Gettysburg filmed in 1993?

Did all of you like the movie Gettysburg filmed in the early 90's? I thought it was an ok film, they missed parts like showing Ewell and Early....even the calvery engagment after Picketts Charge....these parts were important...Martain Sheen did a great job in the film and so did Richard Jordon but I would of liked to see more accurecy....
