A few words from the LA Times...

"...ravaging parable about the terrible weight that too many modern-day children are forced to shoulder before their time." 

"...in a deft staging, director Randy Reinholz ferrets out the humor in Gomez’s drama, particularly the playful interaction between Sylvie and Carbon – a loving but onerous bond that Carbon must break to survive." 

 
"Tousey and Drummond [Sylvie and Carbon]... are standouts, as pitiable as they are ultimately heroic."
