The biggest loss of this show, it's presentation is that it isn't set in NYC any longer. It's moved to the Bay Area, so it might as well be Saved by the Bell: The HBO Years. Actually, I'll take it back, Saved by the Bell reboot is lightyears ahead of this.
The kid characters are just bland, they are all interchangeable with one another.
As for Isabella Gomez, as great as she was on the reboot of One Day At A Time, she is so much bleh here. And the go to woman when you need mean on a sitcom Christa Miller, she just falls flat. And bringing in Robin Givens for a single episode and her character is sooooooo far away from Darlene in the original series, it just hurts, yes, people change over the years, but not to the point they would be totally unrecognizable as the same character 30 years later.
At the end of the day, whoever at Warner approved this, needs to be taken out back and shot. Either that, or you pull the series for a year, rework it. Put it back in NYC, besides the fact the city lends itself more to diversity than the Bay Area, used correctly, NYC in and of itself is a character. Plus it makes it easier to have various character call backs even if they don't appear on the show.
Seth Cohen, Michael Elias. And Rich Eustis dropped the ball on this reboot. They don't get the good of the series, and have written episodes that aren't even memorable in any way, shape or form.
