It's important to look outside your own needs and understand the purpose of this camera, it exists for journalists. High bitrate, 4K ability, integrated lens - this is meant to shoot pieces in the field for broadcast, leaning towards the guerrilla journalism side of things. Protests, war-zones, anywhere where you'll want to be low-key, this will do the job well.
The original C300 was used to shoot the award-winning Blue is the Warmest Colour, definitely no issue with this camera's ability to output a cinematic image. The only issue you can really fault it for is the price, which will come down if it under-performs.
