I'm digging up a zombie here but I watched about half of this and the Irish really isn't up to par. There are a decent amount of grammatical errors, like how in the very first sentence of her introduction she misuses tá when she needs to be using an identification copula. Or in the "don't have sex..." quotation she uses the singular imperatives when iirc in the movie the teacher is lecturing a whole class, necessitating plural imperatives.
The bigger issue though is her pronunciation. She doesn't seem capable of producing the ch sound or the broad gh sound. She pronounces an f in gheofaidh when a) that's not even the correct form of the verb, its gheobhaidh and b) the f isn't pronounced in the 2nd person future in verbs that do have it. Perhaps most importantly she doesn't seem to apply mutations consistently or correctly. It's a cute idea for a video, but I'd recommend you get your Gaeilge elsewhere.
