I thought the first 10 minutes of Ep1 was excellent - the right amount of hubris and ballsy production. Since then, I've just been bored.
The first episode seemed to consist of cars going round tracks and that was pretty much it, the second was a rehash of some old TG military-based ideas with the interminable shoot 'em up bit. The 'speaky' bits in the tent I find dull, with the usual gurning-to-camera and pretending-to-be-idiots routine. It just all looks so tired as a formula. The one section that could have held some interest - the wheel spinners - was just glossed over with no attempt to examine the culture behind it.
From around 2004 to about 2009, I thought Top Gear was genuinely warm, funny, intuitive and original. I kept watching since then as it occasionally came out with some gems - mainly of a more serious, documentary nature. But the later Top Gears, and now GT, strike me as having poor scripts, a complete lack of fresh ideas and very little entertainment value.
All humour is basically subjective as a guy earlier on here said he was having hysterics at Ep2! It didn't raise a smile with me I'm afraid.
