The Spider-man films have largely been very successful! Part 2 equally sucessfull! Part 3 is certainly full of extraordinary effects, but seems a bit cluttered and not as balanced as the other two parts. I was not really disappointed by part 3 but not enthusiastic.
Now for the trilogy box:
The 3 parts (Spider-Man 2 in the 2.1 version Extended) are each as a single DVD edition so in a simple slide. The slider is fine but does not have a stop and admire. A little bonus material (audio commentary & Spider-sense)
I think those who want to watch the movies now and again with this box is well served.should treat yourself to the various Special Editions. The price is in my opinion still fine.
