The former How I Met Your Mother
star's hosting stint
received some mixed reviews -- many loving his opening number
, but criticizing him for mispronouncing some of the stars' names
-- but the actor says he didn't pay them much attention.
"I didn't keep up with it obsessively, but it was interesting to see just what people thought landed and didn't," he said of the reviews. "It's so difficult for one who's simply watching the show to realize just how much time and concession and compromise and explanation has gone into almost every single thing. Every joke. Wording of joke. Placement of joke. Canceling of joke. Embellishment for just one line."
