The anime was a good watch, vibrant colours, nice animation, the style is refreshing and the opening song is SUPER catchy . It was not a bad anime but I would not say is a must watch.

A lot of things made absolutely no sense and I expected them to be explained in the end, which never happened and that left me wondering if they even thought about what they were doing - or why they made such and such characters. At times it felt so random that it just seems for me that the anime had a weak plot and the staff had to randomly drop some ideas to make it seem like the plot was deeper, while in the end a lot of the secondary plot points introduced mostly in the beginning of the show ended up not mattering at all because of the greater plot introduced half-way.

The show had a lot of tone shifts, the comedic parts would sometimes come right after the more serious moments, making me have no time to have any feelings for what ever happened and making the seriousness of the plot rather a joke. I feel like they tried to make the show both dramatic, funny and ecchi all at once and what came out from that was a mess that made me have no reason to get invested in the anime whatsoever, it caused me to disconnect with the story and characters in such a way that if a character would die or if the planet would have exploded I would not care slightly.

The characters are forgetful, although not irritating they are also very blend, nothing I have not seen in hundreds of anime, not one character catches my attention and I feel nothing for the main character even with all the dramatic back story.
The music was OK, I had the opening song in my head for days, the ending is also nice, the OST worked well with the show's visuals.

All things considered though, I must say that it was a fun watch, the anime is just really well done art-wise, it is a shame that it lacked so much in the story department.
I would recommend this anime for people seeking for an easy-going experience, the anime is rather short and is sure very vibrant. I would also recommend anime like FLCL or Tengen Toppa Gurren Lagann as a better version of what Punchline was trying to achieve.
