(un)watchable?

In one of the great threads ever at YFSF, Nick asked our readership who they most like to root for and against, and who they would trade to their rival or take from their rival if given the opportunity.  In a fit of unoriginality, I am taking that question and altering it slightly: who are the players you least like to watch or most like to watch.  This may be a subtle difference from Nick's inquiry, but there are players I really dislike that I love to watch (late-career Roger qualified) and players that I like that I can't stomach to view in action (Tim Wakefield certainly qualifies on that list, perhaps unfairly?).  There are many reasons for this "watchability factor": technique, form, visage, gutlessness, likelihood of implosion, etc.  So, who are they?  We want names and detailed explanations. It's subjective, no judgments will be rendered.  At least not at first.

My starter list (Sox-centric, for obvious reasons), sure to expand, is after the jump.

Current players, "unwatchable"

Julio Lugo, Tim Wakefield, Tek (at the plate)

Current players, "watchable"

A-Rod, Papi, Manny, Paps

All-time "watchable":

El Tiante, Pedro (#1 of all time on my list), Roger Clemens, Will Clark (who doesn't love to watch a brown-toothed smooth-swinging lefty first baseman? Seriously, who doesn't love that?), Wade Boggs at the plate at his peak - artistry.

All-time "unwatchable":

Bob Stanley, Pete Rose (however great, he did everything ugly), John McNamara (if it is possible to find a manager  unwatchable), Dennis Eckersley (particularly in his Oakland days).
