If people want to hate on these two, there's not really anything to be done about it. However, it might be more understandable to me if there seemed to be a bit more legitimacy behind people's complaints.
The biggest complaints regarding Sheamus, seriously, have been about the guy's almost inhumanly white skin and his friendship with Triple H. Firstly, the skin issue is more than just a bit ridiculous. The guy is full blooded Irish and, from what I understand, they don't tend to tan all that well. Even still, I hardly see that as justification for all the hate he receives. As for his friendship with Triple H, so what? People, think about it for a second. Vince McMahon is the owner and chairman of the largest wrestling promotion in the world. A company which makes hundreds of millions of dollars a year each and every year so do you really think Sheamus is going to get a push simply because he happens to be friends with Triple H? Do you honestly think Vince McMahon would allow Sheamus to be in the spot he's in unless he actually saw something in the guy? Don't you think it's possible that McMahon sees some talent and capability in the guy? Since Sheamus has been in the WWE title scene, he's cut a couple of good promos, has generated good heat from the crowd and has gotten people interested in the Raw main event scene. With Sheamus in the picture, I haven't heard the words tired or stale being casually tossed about. Whether people like or dislike Sheamus, he's generating renewed attention and interest in the main event scene and that's one thing that Raw has definitely needed.
As for Drew McIntyre, I don't really see what anyone's problem is. He's also cut some good promos, he's involved in an interesting IC title feud with John Morrison, he's another young guy that's come along and has generated some interest. He's gotta great look about him and yes, he's also friends with Triple H. The same thing I said about Sheamus applies to McIntyre. If McMahon didn't see something worth something in the guy, I don't think he'd be where he is at this particular point. Nepotism might get your foot in the door, but one is gonna have to be able to show something before they're able to walk on in.
I'm not saying that McIntyre and Sheamus are the best of the best of the best or anything like that at this point, but they're not bad either. They're definitely not as bad as some are trying to make them out to be. They've been booked similarly sure, credit some of that to lazy booking I suppose, but there are enough differences between the two that I don't find it annoying.
People on this board have been screaming for much of 2009: "We want somebody new" or "We want something different" or "We want something unexpected". And, lo and behold, the WWE does provide all three aspects in a short space of time. And still, people complain. Even if there's nothing truly relevant to complain about, they'll still find something to piss about even if they have to take the most mundane and meaningless thing, i.e. Sheamus' skin, and run with it.
