Clare Newsome:4) The CGI has fared well in the transition to HD, though some poorer moments - notably the tigers - haven't improved much (if at all) since the unconvincing original!
Agreed. Watched it the other day. Tigers scene still looks ropey in the bits where there are tigers and cast in the same shot. Worse still was the scene where Commodus returns to Rome, climbs the stairs and receives some flowers.... Awful! So washed out it's almost black and white, and fuzzy too. Replacing it with storyboard animation wouldn't have looked much more out of place!
Unlike most other action movies I've watched, the subtle effects and primarily the music (which is great), seemed much more impressive than the bombast of battle scenes.
My next gripe is the directors "introduction". An introduction in name only, telling us in not so many words that there'll be a director's cut in the future. (What is it with Ridley Scott and all his different cuts? Blade Runner must be up to around 7 or 8 different cuts by now!)
Overall, would agree with the consensus that it's great film, more so in this extended version, but not the last word in HD 'jaw-dropability'.
