I've watched the first three so far and have found all of them enjoyable. The (then) recent transition away from silents was evident here and there but for being so early in the sound era, these shorts hold up really well. I've noticed that in several 1929 Roach shorts - they adapted pretty quickly to sound.
Jay Eaton in the Big Squawk was a low point. He could lull someone to sleep with his tone in that otherwise very fun and entertaining short. Chase's makeup in that short also seemed like something more out of the silent era.
A couple performers in these first three shorts had tragic endings (not including Thelma Todd). Anders Randolph, who I thought was really good in Snappy Sneezer, died at age 59 in 1930 after what the Lord Heath website called a "relapse after surgery."
Earl McCarthy, who was in Leaping Love and Crazy Feet, died of a heart attack at age 27 in 1933, according to the Lord Heath website.
