I just saw it.
If they're gonna re-use the same jokes, do it right. In the original, when JEN says "Sending e-mails, receiving e-mails... deleting e-mails... I could go on", she pauses and then stops talking because those are the points where we laugh. In the remake, she doesn't pause and goes on naming things (screen, keyboard, etc.). The problem is that the e-mail part was the punchline.
That being said, re-using the opening credits (and placing them in scene transitions) and the theme music in a remake is just lazy. Specially because the 2 new actors have different hair from their counterparts, so the animated versions don't match.
We didn't see much of DENHOLM, but I felt that, if the show had continued, he would've been a more realistic character. But he worked as a cartoon in the original because of the absurd humour.
Joel McHale is better than Chris O'Dowd, even if he's too good-looking for the role. Richard Ayoade is doing the exact same thing but he's great at it. Jessica St. Clair is terrible.
