The visual novel version of this is probably one of my all time favourite media of any kind, period. It's laugh-out-loud funny almost always that it wants to be and the slow build up to the climax makes for a hell of an emotional rollercoaster.

I'm not quite sure that this anime matches it in pacing or humour/dialogue (but this isn't a slight against it, the original was just very very good). However:

This is beautifully drawn and animated. Direction is unique and experimental. Audio work is very well done.

Overall, I'd say that this adaptation has really brought the characters and world and Steins;Gate to life, even if it suffers from some pacing issues due to it's format.

For those unfamiliar with the original work, expect: wacky, endearing characters, time travel (a surprisingly grounded take on it with only one or two liberies taken) and a good many feels.
