You'll enjoy it.
Watched it a couple of weeks too. It doesn't get worse but at the same time, it doesn't scream out 'Wow'. It is enjoyable if you don't want anything too serious but it is light-hearted.
One thing I hated about it is that it's clearly set in America (left-hand drive, the branded US-style uniform, general setting of the school) but everyone has British accents. I'm not sure if that was an oversight of it all but I had to get over it to enjoy the programme.
