I added the 1 1/2 cups of milk and mine wasn't soupy at all. It's actually less milk than the pudding box calls for. It doesn't have a strong lemon taste though. I like my cheeks to pucker from the lemon taste so next time I'll add lemon zest and/or juice to amp up that lemon flavor. And make sure your cream cheese and milk are 100% room temperature. Otherwise you get little pearls of cream cheese in the mixture. Still tastes good just looks funny.

I just made this recipe this afternoon. I knew something was wrong with adding 1 1/2 cups of milk. As a result of so much milk, it is soupy. I suggest next time no more than perhaps a half of cup of milk. Gradually poor it in with the pudding mix. Do no add the amount of milk the recipe calls for.
