Most Helpful Guy
I have a huge problem with statements like "the next..." or "the male/female...". Why can't she be herself, without the comparison? As for whether she has that range, Meryl Streep has been acting for a very long time, so there's quite a way to go before this kid could have a comparable career.

I really hope her and all the IT/ST kids turn out okay. They seem to be doing pretty good (aside from Jack Dylan Grazer but he's like 14 he's got time to get himself together) so I'm pretty optimistic.
The distinction I think is their parents didn't make them act, they wanted to. A lot of child actors I've seen have public meltdowns were often controlled all their lives by parents then agents then a hollywood entourage so the second they can get away from it they lose it.
And I don't know about next [whatever celebrity] but if she's this good an actress now I'm sure she can get even better in the future.
