If Celine had tried she would have been way more than an ok actress. You can easily tell. Same way it was obvious with Gaga from the start just from music videos. These two first English Celine albums are different to the ones that came after. Her voice in these ones was a little bit hidden (not in the live performances alone, which gave her that aura Whitney had of surpassing her recordings in live shows). Her following albums were way more universal. But some aspects of her voice in these eras were very special too and never came back (because voices change with age obviously, sometimes in just 2 or 3 years).
