Review Detail of John_Annex in The Ocean Lord Is Unusually Powerful

Managed to get to ch.40 before I had to just stop, the MC is just not that interesting at all and his personality is just flat, the units he recruits are murlocs, nagas,and sea pixies and are just about as uninteresting as it gets, when he recruited his first hero unit I thought there might be some actually dialogue but nope, she says less than 15 words in 20 chapters.
