The first striking point of Kyoryuger, as seen in the first two episodes, is how energetic that series is: plenty of action, and of course, plenty of hot-bloodedness, which pretty much fits the dinosaur theme of the season. Moreover, even if we begin to learn the background of the heroes, the series takes its time to have them know and appreciate each other. In contrast, Go-Busters, especially in its first episodes, was pretty low key, and rather focused on explaining the drama that the characters have undergone when they were children, the importance of Enetron and the general context, and all the characters had a pretty serious tone, and shared a similar background.
Another major contrast is that Kyoryuger's designs ( especially seen with the Kyoryubase, the villains, and even, in a way, the mechas) are colorful, fun looking, when Go-Busters's designs were more stern and more dull.
While Go-Busters had a very "professional team" feeling, Kyoryuger looks more like "a bunch of misfits put together to fight an enemy force".
Now, more insight about what I think of Kyoryuger based on the first two episodes; my feelings are pretty much the same that those I had when watching the scans and learning about the heroes's background, the supporting characters and the villains.
The heroes are, as I said, pretty colorful, all showing a real personality. Even if Kyoryuger doesn't avoid the stereotypes (Red being hot blooded and enthusiastic, Blue is the soft guy, clumsy and unsure of himself but overall a good guy, and Pink, a rebel princess, who wants to be (and in fact already is) a badass princess), the series uses them nicely. Moreover, the supporting characters seen so far (Blue's sister and niece, and Pink's servant) help make us care about those heroes, because it makes their personalities feel more human. It's gonna be interesting to learn more about Green next week, especially his relationship with his father (besides, having Ayumi Kinoshita (Dekayellow) and Junichi Haruta (Goggle Black/ Dynablack) (to be seen next week) is always a treat. Even if we don't know a lot so far about Green and Black (Green is gonna have focus in next week's episode), they seem to have potential as well.
Torin is a very nice surprise: while in the scans he looked pretty silly, his voice actor is great, and perfectly makes the big bird (or perhaps feathered dinosaur) feel like a mentor figure.
The villains are a mixed bag: while they are pretty colorful, I don't feel they have much potential, storytelling wise, because they seem pretty much one dimensional ; Chaos seems to be an adequate villain boss, but his underlings look more like a silly bunch. However, seeing three of the generals leave the base to go to the field, with Aigaron even fighting was nice; (and Dogold is likely gonna fight next week) was nice. Another nice idea was to have the mooks being able to assemble together to make big monsters; it's a nice twist from the usual "becoming big" mooks seen in Shinkenger and Gokaiger.
The action, the mechas, the weapons are pretty fun so far, with a fun use of the dinosaur theme, and the samba stuff isn't too much invasive.
Kyoryuger has a nice beginning. However, like a lot of recent sentai series, it is a risk of suffering from plot stalling, especially given its relatively one dimensional villain group, and I really hope that Riku Sanjo is gonna write a worthy storyline for Kyoryuger.
