Not their best work, IMO. Half the thing is a bunch of runnin/gunnin, trading bullets in the rocks. It just wasn't as fun to watch as the elaborate choreography of close-in combat, which I thought was kinda the staple of this series.

There's plenty of nits to pick, but here's a few of mine...
I know Cap is super-human strong and all, but I just don't buy that he could throw around the ~1000lb Chief like that. Also; apparently the Master Chief had his energy shields off for this fight, in what, the interest of fairness?

The one move I DID think was pretty fun was when Cap returned Chief's sticky grenade back to him on his shield. That was a nice use of their "special" elements, but that was about the only one.

Sure I didn't care for their ending, but that's just a result of their voting process - it's not like they actually analyze who might actually win these match ups - but I didn't dislike it for that reason alone. Even if the Chief would've won, if it still looked like that, it was just... boring. :-/
