I think the show is pretty solid. It does a good job of showing him being beaten down by trauma and how the experiences of his past life shapes his current thinking and how he approaches certain situations and how he eventually overcomes them with the help of others.

A lot of isekais just have the characters reincarnated and then they just forget their past lives and move on. I think Jobless does a good job of reminding you that this is his second chance.
