It was a surprisingly good, utterly predictable but not hugely irritating episode.
Chuck is just, all the "love" stuff as opposed to them on missions is not just cheesy and corney, its painful to watch.
AS others are saying, it started off well, but, in anything in life, you do something enough you actually get good at it, him still being a stuttering, clumsy idiot who can't say anything right 4 seasons later is painful, not funny. Characters need to grow, it doesn't always work but it has to happen. Chuck is the same guy from the first episode, and he still does the cringe worthy pop shot face every time he has to fight anyone and the insanely embarassing "loading up skill" thing is also a joke.
IT started off semi serious with a lot of slap stick stuff thrown in but has become completely slap stick, lost most of the comedy moments and gone round in circles for ages.
As with so many other shows, good premise but tame to poor execution, it should be a LOT better than it is.
