I just came back from Borders and after reading the "official guide" and seeing the pics in there I really think that they should re-insert the Smallville sequence.
Based on the pics in the guide, they really did cut what I think is a vital part of the movie. Basically the entire SV sequence is the ONE sequence that I think will probably satisfy all of those haters b/c it appears as if the SV sequence is entirely dedicated to the one thing SR should be more focused on--Superman's return. This part is all about Clark questioning whether or not he should suit up again...Plus it would give Martha some much apprechiated screentime.
I hate that the Kents are brushed off in the movie continuity.
