The only bad thing about streaming is that you're continuously paying for content that you'll never own outright. I have a Netflix subscription, but I buy Blu-ray discs and DVDs too.
This! I like owning physical copies of my favorite shows and movies, because it can be so unpredictable as to when certain shows are removed from a streaming service. Being caught in show limbo is the worst. I'm in the US, and I remember when Doctor Who was taken off of Netflix. I'd gotten really invested in the show, and I couldn't finish because the show was gone from the platform.
