I find Hamster and Gretel to be quite an interesting show. The premise of a little girl and her hamster getting super-powers from an alien whilst their brother Kevin gets nothing except to drive them around in the family mini-van. Their adventures make up the show, but there is so much more there than a simple children's show.
The musical numbers are good in their own right. The music is played as if it is a serious song, but when you listen to the words you realize it is actually very witty. Plenty of references that will go over the heads of kids, but with meaning for adults. Nothing spicy, just modern references that are funny in their song usage.
The main character actors do a wonderful job. Both Hamster and Fred with their dry humor are hilarious. Gretel is caught up as a little girl with super-powers, but she still wants to do little kid things. Kevin has the usual challenges of a teenager trying to get a date, but at the same time watching out for his super-powered little sister. PThe characters and their struggles to be good or bad are played for the humor. Listen to the voices as there are many famous actors playing characters in different episodes.
I found it an enjoyable way to spend some time watching a show that does was done simply to entertain. Hopefully others find it as much fun as I did.
