Well I figure I'll write a more positive review since the other two are more on the negative side of this show. I have nothing against their reviews, I just figure I'll write one that shows the good quality of what made me enjoy this show. And I will say it's not for everyone, as it tackles a topic that some won't understand or appreciate as much as others. And I'm not talking about the relationship aspect of it, but more with dealing with death, loss, and depression.

So with the not spoiler free review lol... here we go...

Blue - often can stand for many things. As we look at the ocean or sky, we see how open it is, representing freedom and life. As we know there is more life in the deep blue sea there anywhere else in the world. But also at the same time, we know blue can also stand for sadness or depression (feeling blue). Blue Spring Ride, depends on how you see it, I feel like it capture the two, as they are off the same coin.
We open up with the two lead character in a very beautiful scene. We also see how it is raining and you know what color usually represent rain, blue. And rain often represent either new life (mainly spring) or sadness (tears). As the character grows and goes through different trails in life, as they face different issue, either with dealing with letting go or finding new friendship.

First let's get the friendship part of it out of the way. I don't really want to spend too much time on this part of it, though not saying it isn't important.

Basically we start the series with Futaba having these friends who you can call "friends." Where she just wanted a place to belong and fit in. And anyone who's been too high school will know how hard it is to enjoy school by yourself. But this never felt genuine as she can never really be sincere in this friendship. She just tried to belong and fit in but when she finally show how she really felt, she loses her "friends." It isn't until after this that she befriends Yuuri who she really can be herself. Building a true friendship, one where she can be sincere. There's more you can talk about the friendship part of it but I'm not really in the mood to say much about it. As I often talk about this too much I'm just too lazy to write it out, so my apologize if I am sort of not fully writing out my whole thoughts on this part of it.

Romance

Honestly there isn't much to say about this part beside, if you really want the romance aspect of it, it's best to pick up the manga. As the anime barely even touch the surface of it. As it just gives us sort of, "will they or won't they." I mean I don't hate it, but I'm just saying, don't come in here expecting a romance anime where you are left with feeling satisfied. So that's all I really have to say about this. And the other romance subplot is just kind of there.... I feel like that if I was to say is a negative... sure I guess? Since it kind of got introduce but didn't really go anywhere. But no I'm not complaining about it lol... I'm just stating the obvious fact.

Loss, depression, and letting go... I feel like this is more of the core theme of the show.

You only know what loneliness feels like once you feel what it is to be loved. When you no longer see the person you used to see, no longer hear their voice, knowing they no longer are around. Everyone person deals with loss differently. Either that is a friend who moved away or a love one who has pass on. No matter what, it is a painful experience. But the thing about life is that it is always best spent with others and never alone.

"Even if death will eventually tear you apart, it’s better to meet someone than not meet them."

I feel like Blue Spring Ride really capture this more as it's core theme then anything else. Overcoming depression is something that takes time and each person deals with it differently. One thing I do believe is that it is often best with those who genuinely care about you. A burden is lighter when we all carry it together. Some people will shut themselves out and sometimes it's up to us to knock down that wall/door to get to them. As this seem to be the main theme of the show.
As winter will come and everything seems to freeze in time and place, we know that Spring will come soon after. It may be the end of one journey but it will be the beginning of a new one. We want to look forward by having so much ahead of us that we don't have to look back. Our past is meant to be there, but it is a part of who we are. In helping shape you and your future, to helping you grow, learn, and understand that there will always be struggle... but with them comes memories we can cherish. Those friends you have now, one will too be gone, but does not mean they weren't important.

I'll end with this beautiful quote

"All these moments will be lost like tears in the rain."

Agree to disagree with me but thanks for reading to the end. It was a beautiful ride with great visual and a unique cast of characters. A great OP and ED, each setting up and ending the anime beautifully. It's worth a watch, but as I stated if you really want a romance... you have to pick up the manga. (Sorry if there's grammar issue or anything since I'm too lazy to proof read and I just write it all in one go - whatever pops to my head lol)
