The Celtic vs Grid battle was a classic matchup no doubt. Although short, it was very satisfying to watch. Although Celtic lost, it was his own fault, he was dominating the fight, barely giving Grid a chance to retaliate, but once he let his guard down, well, look what happened.....
The "battle" if u really wanna call it that between Scar & the swarm of xenomorphs didn't really do much for me, I was quite dissapointed that the plasmacaster has been changed to that extent. Robbing the weapon of it's classical feel, it was merely a poor, 10 second shooting gallery to me. The biggest dissappointment was that was that it was the only real scene (apart from the pathetic showing in the flashback scene) where a caster was even used in the movie.
