One user on the official "Mom" subreddit started a thread titled "I love Tammy," in which they simply professed their appreciation for Kristen Johnston's "Mom" character apropos of nothing else. In response, the majority of commenters agreed that Tammy is a top-notch character, and highlighted Johnston's acting ability as a principal reason that Tammy is so entertaining.
User ruadhan1334, for example, described Johnston as a wholly underrated talent, capable of both comedic and dramatic performances. Similarly, user miker279 cited her role on "3rd Rock from the Sun" as precedent for her amusing work on "Mom." Meanwhile, user Bindid24 listed Tammy as their favorite character, and concurred with a number of other commenters who described Johnston as a national treasure.
On Twitter too, fans have singled out Johnston as a standout performer. For example, @IsaLeeWolf wrote, "Without question, #Mom is the best show on CBS. And Kristen Johnston somehow made it even better."
In an interview with The New York Post, Johnston shared some insight into her approach to playing Tammy on "Mom." "I'm a theater actor, so my instinct is big" Johnston said. "Let's put it this way: no one's ever told me to go bigger."
While "Mom" may now be over, Johnston is set to join the cast of "The Righteous Gemstones" Season 3 (via Variety), meaning that her numerous fans can still look forward to what may well become another standout comedic performance.
