The name Valerian repeated 63 times in the movie

The characters repeat the name Valerian so frequently it got really annoying and especially noticeable in the scene where he is pursuing the ship with Mul aliens. That scene starts at around 57 min 50 seconds mark in which Laureline calls his name 18 times in the span of 6 minutes! It makes me wonder how much of this script was improvised.

Apart from that, Neza's delivery of lines was so flat I thought it was his first role but it turns out he acted in other movies before.
