Looks like the Lindsay Lohan comeback train is stuck at the station, after her roundly panned hosting gig Saturday on "Saturday Night Live."

"This may be the first time Lindsay Lohan had trouble doing lines," cracked the Twitter user @drunkenough, after the bad-girl starlet stumbled through a series of sketches in which she appeared wholly reliant on cue cards -- and sometimes seemed to have difficulty reading them.

"Worst host of the year?" EW.com asked in a headline.

The return gig as "SNL" host was supposed to be a professional highlight for the 25-year-old Lohan, who's struggling to get her career back on track after her most recent round of troubles, including well-publicized substance abuse and family turmoil. She described her recent court-ordered community service at the L.A. County morgue as "humbling" and "a learning experience." Her nude photos in the January/February issue of Playboy magazine drew widespread derision.

But the "SNL" blowback may prove worse, if the early reaction is any indication. "She looks scared to death out there," observed Hitfix critic Ryan McGee. And that was one of the kinder reactions.

"People are saying Lindsay Lohan looked tired and worn out hosting SNL last night, but I thought she looked fantastic!" tweeted @ILNY83. The accompanying photo was of Betty White, who hosted the same program in May 2010 -- at age 88.

Another widely retweeted thought: "#SNL had Lindsay Lohan on mainly so NBC News would have fresh file footage next time she's arrested."

What did you think of Lohan as host? Can she engineer a comeback?
