[Pako]

In regards to Steins;Gate and the main character being "over the top": this probably won't make his antics any more bearable but maybe put them into some much needed context which the anime is kinda bad at providing. After his childhood friend, Shiina Mayuri, lost a grandparent she fell into a kind of PTSD, which caused him to assume the persona of a mad scientist, claiming he'd take her hostage because he didn't want her to go/leave. This helped her get over that death somehow but he still regularly lapses back into that persona.
