Practical effects usually last longer
Compare "The Thing" with Kurt Russell and the Remake
You're damn right. Funny thing about the 'prequel' - they did begin using the prosthetics and practical effects and were making good progress. I forget why they opted for the CGI in the end but they did genuinely start off down the right path. My favourite thing about the prequel is the tie-in at the end with the helicopter chasing the dog... Such a great way to line it up with the original. It's a shame but that movie could have really been a great thing. The Thing (original) is one of my favourite movies full stop.
CGI works well when it's used minimally - like Terminator 2 - over 30 years old and still holds up for the most part in terms of effects. Obviously not brilliant but what they achieved - literally the icing on the cake. Now it's plastered all over the shop. Kind of like steroid abuse in modern bodybuilding.
