Has anyone else read The Borrowed Life of Frederick Fife and disliked it?

I've tagged this whole post for spoilers because I'll be talking about the plot a lot.

I'm reading this for my book club and everyone's loving it. I don't know what book they're reading because I am finding it a total slog. I have a few issues with it.

1. The fart jokes. It's bizarre to have fart and burp jokes and then the next page have characters crying in grief. I understand obviously that books can express a range of emotions, but I just don't think this one does it very well and I feel both the jokes and the poignant moments take me out of the story when juxtaposed against each other.

2. The author has no choice but to portray Frank as the nicest guy on the planet because they need us to root for him despite him stealing a dead persons identity and family. Because of this, he feels incredibly one dimensional and also contradictory. I don't believe a person as nice as Frank is portrayed to be would be able to look Hannah in the face and, for instance, give her that bird house. Imagine being so selfish that you'd make a girl think she was reconciling with her estranged father when she was really just talking to some guy. I dislike the character of Frank as I feel I'm being manipulated by him, so its hard to get on board with this book which relies on the reader finding Franks actions heartwarming and charming.

3. I'm bored of reading about fat characters that hate themselves. I detest when authors use 'waddled' instead of walked, and 'plonked' instead of sat when they're talking about fat people. It's a personal bugbear of mine and comes up so often in this book.

4. I know it's not supposed to be that serious, but in a world where sexual abuse is rampant in nursing homes, it's bizarre to have the author of this book, who worked in a nursing home herself, make light of unwanted advances and groping. I find it really distasteful.

5. Similarly to the above, it feels infantalising to portray somebody with dementia as a happy go lucky goofball. It gives me the same uncomfortable feeling I get when people with Autism are described as being 'like superheroes'.

6. The whole tone of the book is very bizarre. The nursing home feels like some sort of school camp and doesn't feel grounded in reality. On the other hand, the discussions of grief are very real. I think the author has tried to do that thing where the emotional moments are more like a gut punch if everything else is lighthearted, but I don't think they have done it very well in my opinion and it gives the book an unrealistic feeling where the whole time I'm reading it, I remember I'm reading a book instead of being lost in the world and characters.

7. This is a tiny nitpick that doesn't bother me much but it feels like the Australianisms are over the top. I live in a small country town in Australia and even I don't hear this kind of language haha.

Does anyone else agree? I can only find positive reviews and my bookclub love it. I need to know if I'm missing something!
