Pat himself admitted that Twilight Zone in its final form only happened on the back of the success of Addams; and even then he should never have been allowed off the leash as much as he was and it would never ever happen in the industry again (though JJP Pirates may have proven him wrong). TZ is very much an outlier, as are his later Stern years where there wasn't nearly enough allocated resources to do his designs proper justice. But even with CSI during the leanest Stern period, you can tell Pat was still putting all the effort he could into his layouts.
