Looking back on it now, the actual crash does look pretty dated. But it is still well done, given when it was made, etc.
One thing about the evacuation that has always puzzled me: why was Sickbay evacuated?
Sickbay was on deck twelve of the Saucer Section, close to the centre of the deck to afford it as much protection as possible. No medical facility was ever established as being in the Drive Section, though it would make sense when the ship was separated, so as to treat casualties during a combat situation--but why would Beverly be there instead of the main facility?
The sickbay in the saucer isn't the only sickbay on the ship. In fact, given that the stardrive is the bit that is more likely to go into battle, it would make sense it has medical facilities there too. You wouldn't want your crew to die just because the saucer took the hospital when it scampered off.
