This only my third Super Sentai series- however, I found it overall light hearted and enjoyable. The premise was a good story- and the Villain designs were really beautiful- and Zett was a great baddie. The heroes seemed a little less formed in some ways- Kagura was by far the weakest character but my favourite was Tokkachi closely followed by Akira. The opening and themes I liked a lot. They get stuck in your head. The story line at first seemed a little too simple but this has some great foreshadowing worked in and as time goes on it becomes more complex. a series well worth watching. And for those who worry it might just be a knock off of Den-O then don't worry it really not!
