Honestly, it was pretty much a constant sugar high from divergence to end, specially after the hell holes that were ending 1 and 2. The visit to the Aquarium was adorable and unlike in route 3. Lucy didn't become emotionally frail when confronted by Trish and that allowed things to get cleared up oh so much better, that simple "you humilliated my boyfriend, I'm pissed, fuck you and give me time to cool down" conversation on the roof avoided so much bullshit. Hell, the route even managed to get me to kind of warm up to Trish (though something tells me a real life equivalent would have been a lot harder to get off the Kool Aid)... and when she's an adult she is a fiiiiine looking Trigga.
It also had those great pangs of humor. Naser's Monkey jacket got a huge chuckle out of me as well as the "no Mr Spears, I'm just taking the word back" and "Homo History Month". Also, the Ye campaign joke with Naomi hits SO MUCH MORE today than when it was originally added
Though I liked Chadnon more, Lucy is definitely at her best in route 4, hell, that she managed to patch things off with Naomi speaks volumes.
As for other characters. Naser is my favorite supporting character. Finally got the deets about the crippled wing and was kind of surprised that all of Lucy's trauma pretty much came from that single event and it all just spiraled out when she stuck with Trish and the stupid bitch found Tumblr. At least now I know what Naser and Lucy talked about in Moe's joint during Route 3. And well, he is just a bro no matter what route you are in, even though he's a huge doofus at times.
Spears is also an awesome time, if schools had more principals like him a lot of stupid shit would just be cut from the root.
Reed is probably the character that disappointed me the most. He seemed like the wise stoner but pretty much in all the routes he just defaults to going with Trish's bullshit even when it's obvious it's not a good for anybody. Guess he was just a stoner that had moments of brilliance and a crush on Trish.
As for Rosa, she was fine for what she was needed for, though I expected Stella to be a bit more relevant since she does seem the pseudo 4chan stand in. But it was a fine ensemble, I did get a special liking to hot dog lady and taxi guy.
Now I just have the bonus scenes left, specially looking forward to what Metal Gear Raymba has to say
