The FS version has often been the cause of many a heated discussion.
As soon as someone says they don't like it, or prefers a different version, the FS lovers come out and claim you're just jealous because you don't own it. I lose track of how often this has been said to me. It's not just IM though, it's usually the first release of anything that gets put on a pedestal.
In the early days, I wanted to own the FS IM, naturally. I joined the party late, my first steelbooks were HMV's Thor and Captain America. Obviously I wanted to get all the Marvel titles but I wasn't about to spend stupid money on them.
At the time, I ordered the Korean version of IM2 which I was happy to own. It had a nice weighty feel and great embossing. I hated the blue banner, but it was the only one I was aware of. I would have liked IM to go with it, and eventually I would have cracked.
But then...
Play announced their IM releases and, wow, no blue banner on either of them. Fantastic. I ordered straight away and got shot of my Korean IM2. I was more than happy with them (after swapping out the inner plastic making them 3 disc sets). I know what some will say, the FS IM feels better quality, true (assuming it's like the DVD steelbook which I owned), the colours are richer, true, and it's a grail in terms of rarity, certainly true. But regardless of these facts, I still prefer the Play version.
This is nothing against those who own the FS version, or any release they love. We have different opinions and we're never going to agree all the time.
IMO, and it is just my opinion, I prefer the Korean edition of Days of Future Past over the HMV version. The German Blade Runner over the UK white one. The US Watchmen over the Play version and the new UK release of Taken over the original Play version. You may agree or not with my choices, but I like to own the versions I like the most. These are the ones that appeal visually to me.
