I just noticed the first episode available "On Demand" so I finally got around to watching it, and boy are most of my fears confirmed. (Hopefully the following episodes go in a completely different direction)
There were just way to many similarities to the first series, with some scenes and dialogue matching exactly. Add to that the group of boys, where the two supporting characters are Masume and Manabe to a T, as well as the mother being a mashup of Miyaji and Kamon. This all just feels like a way to cater to the people who, if this played in a theater, would start cheering when they used a song from the original or when Haruko arrives (which errr they kind of did for us in the series itself) because thats what they believe they are supposed to do.
There were one or two areas, that if they follow, could make the series really good, such as who is Hidomi's mother and what is her connection to the first series. But they could also easily fall into a trap where the show is pure fan service and plot points completely disregard the original, such as making Haruko pull robots out of the children's heads just for kicks, as opposed to her original goal of finding Atomsk.
I think what made the original great was within the madness was a great love story, and if they just go for wacky randomness we can see this was just a money grab.
