I saw it last night, and the episodes were OK. I REALLY like the casting of Milioti as the Mother, though. I thought the producers would go for a more familiar or famous name, or bring back one of the ladies that Ted had dated before, but first seeing Milioti's face on the train station during last season's finale was a VERY pleasant surprise. (Loved her on Once: The Musical, and I can see a song and dance number with her in an upcoming episode)
Also, really liked the chemistry between her and Lily, and Ted, based on the eps last night.
