Am I crazy for building up a blu-ray collection?

[PCFan]

About 1 month ago I started collecting blu-rays again. Before then I sold all my blu-rays to a 2nd hand movie store, most of the ones I sold in my opinion were not worth keeping but a few of them I regret selling, especially when I didn't get much for them. I rebought a few blu-rays that I once had that I regretted selling last year because I found good deals on them. Now I have 50 blu-rays in my collection. I probably spent about $8 on average for each movie plus Best Buy rewards certificates helped lower the price even more on some of the ones I purchased from Best Buy. A family member was advising me not to buy movies anymore and just rent them or Netflix stream them. I still use Netflix and Amazon Prime subscription services for streaming some movies, especially ones I'm not sure I would want to buy.
