Saiki Kusuo no sai-nan

Honestly this was so refreshing! The cast is so colorful, and they play up their anime counterparts so well. As someone who's enjoyed the anime, I think they did a fantastic job translating everything into live action. The low-budget effects of the floating cars and fake backgrounds really lended themselves well to the gags.

I especially loved how well the main character kept a straight face. It almost felt sometimes that he was almost about to burst laughing, but he always kept it together. I also thought the wigs and costumes were done especially well. It's obviously fake hair, but with how colorful the uniforms and setting is, everything blends quite well. The fact that every character is ridiculous, and strange occurrences are dismissed really helps with immersion. Instead of focusing on how bizarre their world is, the characters allow the story to move along.

The short of it is this: this is a live action adaptation that stays true to the anime (it doesn't try to re-write any characters or anything frustrating like that!). It is colorful, most of the acting is quite good, the gags are funny, and it's light-hearted. This isn't some deep drama, I'm surprised the other reviews are so low. If you enjoy the silliness of the anime, it's reflected quite well in the live action, especially considering the budget and that it is real live people.
