I think you're alright.
No great love or dislike of you.
Often find some US reality shows a bit too much, can't say I'm too keen on your gun laws.
But, you're a much larger country than us, with possible complicated law changes from state to state, we're tiny in comparison and the whole land, made up of different countries to make the UK all follow the same laws. I think there are clear differences, I guess we've also a lot in common, which is more obvious and shared as we speak the same language.
On the whole we're a more reserved people with our emotions, whereas Americans tend to be the opposite, and therefore we can be perceived as stand-off ish and you can be perceived as too in our faces ( these are generalisations) you're also perceived as being quite a religious country, whereas we're not that into all that anymore ( don't get me wrong it exists, but that's a general observation)
The American government is usually questionable from over here, there is a perceived arrogance of the way your government does things, I've met and spoke with a few Americans, and there is often an air of arrogance, but that could possibly be the forward and in your face trait I referred to earlier.
On the whole, you'll rarely find anyone here who really dislikes America and her people.
