Ron's gone wrong - film

[Adventuresat40]

I was thinking about taking my DC with friends to see this film over half term. However, I have just seen it is a PG. I saw the trailer when we went to see Paw Patrol and it looked ok, I thought it would be a U.
The youngest child in the group is 4 (reception age).
Has anyone seen it? Will it be ok for a 4 year old?
I have read reviews and nothing stood out to me as being concerning but I would like to hear from someone who has seen it.

I took my 7 year old to see it on Saturday and nothing at all stood out to me as unsuitable. There wasn't anything scary at all in it.

Is it on Common Sense Media website? I always used to find that useful judging what age group a film is suitable for.

Just one review which says 8+

I just can't work out what makes it a PG!
