Watching someone stream it would probably not give the best impression, since most people streaming it are way ahead and they already know what they're doing. I think a lot of the fun of the game comes with discovering it on your own.
For me, the appeal is the laid-back farm aesthetic (YMMV), with a system of resource management running underneath. You start the game with a set amount of money. Each in-game day, you start with a set amount of time and stamina. The only goal the game gives you is to make your farm prosperous.
So each day, you do what you need to do - water your plants, feed your animals, etc. Depending on your outlook, this is either tedious busywork or meditative routine. Then, with your remaining stamina, you do what you want to do - clear some space for new farmland, talk with the townspeople, shop, explore and forage, mine, and so on. You can use the money you make and the materials you gather - create new items for your farm, make your farm bigger, or craft tools so you spend less time on your necessary tasks.
Maybe this sounds boring and repetitive. I don't think anyone would fault you for that. But I find the game to be relaxing due to its repetition.
