I'd be hard-pressed to name any notably bad days at work in the last 6 months, and it's definitely not because every day is stressful. I'm not even sure why you think that's unusual unless you've had jobs exclusively in very unpleasant workplaces.
"Firing the responsible" may be an overly-strong comment -- putting pressure on the line rather than improving line management is the upshot of what I'm getting at.
Though truly boring can be a good sign if it's the result of good planning, drilling, practices, and rewarding competence. If it's from complacency, failure to recognise problems, or the ability to push fault or failure off on others (clients, customers, vendors, suppliers, other departments), not so much.
The good sign then is understanding why and how they got to boring.
