Neh-eh-eh...
No, I'm not going to go with this one. I saw this movie twice (saw it once, then ended up with friends who wanted to see it one evening), and, well, it's got its moments, sure. But overall, what kills it is not the ridiculousness of things like the giant mechanical spider or the booby-trapped train but the fact that the main characters are, well, kind of unlikable and do stupid, arbitrary things for no reason but to get from a to b.
My favorite line in the thing is Ulysses S. Grant referring to West's style as "Shoot first, shoot later, shoot some more, and when everyone's dead try asking a question or two", and a good part of the reason that's funny is because it's bloody true.
Lowlights include Loveless going on about how he could devise a mechanical means of raping Rita (Selma Hayek's character), Rita knocking herself and one of the heroes unconscious in a random moment of panic (yay, we're borrowing one of the stupider plot elements from Star Trek V...), and the out-of-nowhere announcement that the guy they've been trying to rescue is not Rita's father. Also see West setting the sawblades in motion in a fit of stupid pique, Gordon encouraging a mob to lynch West, Loveless' inventory of the injuries that crippled him (which seems, shall we say, slightly out of place with this allegedly "slapstick" tone...)
Look, I'll agree it's not an awful movie despite the laundry list above. But good is a stretch. For every amusing or fun bit, there's at least one bit that's mean, stupid, badly paced or weirdly off-tone. Even Smith himself has expressed his displeasure with the thing; how can one argue with him?
