Suzumiya Haruhi no Yuuutsu, Steins;Gate Recommendations
If you wanted to sound smart you can always take the line from these shows and try saying it wearing a lab coat.
It has a time travel pseudo-science feel and is a sorta slice of life anime with a plot if that makes sense. The jokes are similar and ITS GOT A REDHEAD IN IT!
As I make this recommendation, I am referring to each series as a whole. Both animes have an interesting and complex plot. Both are science fiction, and involve time travel as a major part of the plot.
This movie deals intricately with witty character interaction, good character development, and extremely similar elements of time-travel. The animation and art are both great, and the music will really pull you into the show. There are tense moments that will keep you on the edge of your seat, and there will be light-hearted moments where you can laugh. Either way, if you watch either, be prepared for one heck of a ride!
Important note:The Disappearance of Haruhi Suzumiya is only a movie you can only fully appreciate if you have watched the previous two seasons adapted before it.
The main similarity of the two series lies in the main character and their connection to the characters around them. Both Haruhi and Kyouma are eccentric, loud, and drag their friends into untold mysterious operations. And while the friends outwardly complain, they would not have it any other way.
