I would ignore what ever that reviewer wrote. It doesnt get more basic than Kodak Gold and certainly Gold 200 is just as "Gold" as any other film sold by Kodak labeled Gold.
Start her off on Gold.
Edit: Fuji Superia 400 is only $1.79 a roll for 24 exposures. ISO400 film gives your 9 year old more shutter speed which is probably one of the most important things for a youngster to have. I'd consider using that film.
