Defending m'lady's honor here. As someone who has been subscribed to that channel for a long time, that's genuine. She's one of the few reaction channels that are which is what makes it entertaining to watch and she's very sweet. Her story is pretty interesting too, someone coming from only watching chickflicks to watching pretty much any movie under the sun. Another fun fact, Tom Cruise and the director of MI saw her and her sister react to one of the movies and invited them to the Dead Reckoning premier. Very wholesome event.
I'd definitely recommend watching her reactions to LOTR, if that is your sort of thing. It was pretty amazing watching someone not caring about fantasy to being all in.
