One of the biggest reasons was the colour. Shape and the handle were both great, but the colour kind of ruined the thing as a whole. It should have been released as black, instead of purple.
PS2 had already the brand image from previous gen, so the PS2 momentum was nearly impossible to break, so the "leftovers" was for the others to compete.
Lack of 3rd party support was one of the biggest problems. GC started well, in terms of 3rd party support, but it dried out quickly due to bad hardware sales.
Related to previus point, the mini-DVD hurt in terms of 3rd party ports (despite most of the games fitting to a mini-DVD), Xbox used DVD-9 and PS2 DVD-5.
GC was also lacking the "casual" titles that PS2 had and the ton of cheap shovelware, which both do appeal to public.
The lack of GC being the "hot" item.
And the system didn't really differentiate itself from the competition.
As for the lack of DVD player, i don't see that really hurting GC. It did help PS2 a lot, but it wasn't the main selling point for it and propably wouldn't have been a selling point for GC at all.

Nintendo games sell only on Nintendo system.
