I Purchased This On Blu Ray

I actually have this on regular DVD, but I've been upgrading all of my movies to Blu Ray for a simple better Quality and the regular DVD's, I take them up to V-STOCK and trade them in and receive a store credit which isn't very much by the way. As for the movie?? The MEG is much better than the 2nd movie which really perplexes me how they allowed that to get the best of them when making it and what went wrong?? Problem with the MEG 2 was that they simply spent far too much time in The TRENCH before seeing any carnage, most of which took place at the 2nd half of the movie, not to mention, the dumb subplot involving Terrorists wanting to blow up the Trench.
