It could go either way with 'I Feel Bad.' The show has a fairly simple premise. The main character, Emet, is a struggling mom, boss, friend, and daughter. There's not much to go on there, so it's going to be up to the characters to drive this series. If the characters are fun and have you rooting for them, I see no reason why this show won't be a good time, but if the characters are generic, this will get you bored very quickly.
The main character of Emet is played by Sarayu Blue who has had many roles over the course of her career, though you may have seen her recently as one of the mothers in the blockbuster comedy 'Blockers.' That movie was hilarious, but she'll have to bring much more to the table than the mother role she played in that movie.
