ermmm website recommendations

Hii just came here to ask if anyone had any good websites i can use to watch spider-man across the spider verse? I already watched it with a couple of irls of mine but my dad hasn't and he's been wanting to watch it since it came out but all of the website were in bad quality and he's waiting for a better quality or full hd release of it. so i was wondering if anyone has any recommendations for it :) ? Any recommendations help!
