It was just daft the ease with which she defeated him. I thought at the very least she could take a hit or something (at the time my money was on her losing a hand, seeing as SW is so fond of those injuries), or maybe come up with some Predator-style trap, or have somebody come and save the day. I just always had the assumption that a lightsaber was something that was supposed to require proper training and expertise to wield, otherwise why wouldn't everyone be waving them about?

Also, wasn't Luke Skywalker's lightsaber supposed to be green?
