I've not seen this movie in such a long time so reading this book brought back a lot of memories.
Is it worth the read? Yes, absolutely because you get to know the characters more, through their thoughts and feelings.
I think it enriches the story and I enjoyed reading it, I'm now looking forward to watching it and bawling my eyes out at the ending again.
I didn't realise that the alien was a 10 million year old intergalactic botanist! 😍
