I enjoyed the nostalgic atmosphere of this. The animation, story, all feel like I'm watching a show from the early 2000s.
That said, that's about all I really liked.
I liked the idea of two "enemies" having to be paired up for work, but I wish there were more so-called 'enemy' scenes prior to the partnering up. That way, it could have been more significant and amusing when the moment happened.
Also, the dialogue falls flat. Some of my favorite conversations in stories are the ones between the enemies. However, this did not have enough of that smart, witty banter between the characters Tiger and Bunny. I think that could have helped elevate the show immensely.
The plot, lastly, was just alright. Not enough to keep me thoroughly entertained.
