Out of curiosity, is there anything wrong with the blu-rays or Home Alone?
Home Alone 2 on Blu Ray has a rather low bitrate and the transfer is ok, not great. I have the UK Blu Ray and I think that looks fine but I’d love to see a film scan of it. HA2 has only had one release in HD in 2009 but the original has had three different remasters.
The 2015 Mastered-in-4K 1080p Blu Ray of Home Alone (the original) got raved about on Blu Ray.com but personally I thought it was a bit too dark and over-saturated. The UHD 4K disc (from what I’ve seen) seems to be more accurate. I remember the “Family Fun Edition” DVD being quite accurate to how I grew up watching it on TV/VHS and I assume the original 2008 Blu Ray used that same master.
