It took me a while to warm up to this, but I ended up rather liking it. Definitely a different take on the original anime - the characters and a lot of the situations are the same(ish), but it's not an exact copy. Which is good. It does make for a darker story than the original.
We (girlfriend and I) watched the cars more than the guns.
I really enjoyed the last episode! The previous one was a bit meh, but this one was highly entertaining.
