In the lead role of Danielle in "Shiva Baby", which premiered at SXSW and TIFF in 2020, Sennott's performance was highlighted in several reviews, with Andrew Parker of "The GATE" saying that she gave "a wonderful, star making performance" and Alex de Vore of the "Santa Fe Reporter" writing that "after her performance in [the film], she should probably just be allowed to do whatever she wants – she's a natural." Sennott was named one of the seventeen best performances of TIFF 2020 by "Seventh Row", and won the Rising Star award at the Philadelphia Jewish Film Festival.
