The Gills, who have now won just one of their last 12 games, were second best from start to finish as the Seasiders eased to a comfortable away win.
Goals from Kyle Vassell, Nathan Delfouneso and Kelvin Mellor did the business for Pool, who were even able to miss a penalty as Jay Spearing hit the post from 12 yards.
Lovell, speaking to the club website post-match, couldn't hide his anger at his side's display.
He said: “I have stood up for the players all through the season – quite rightly as they’ve given everything – but today there was nothing. I’m a positive person but there’s nothing I can take as a positive from the first half.
“The second half we had a go but it was too late. We didn’t look like we had a goal in us – it was very, very poor.
“I had a go at them at half time saying about character. It’s having the courage to do things when you’re under the cosh and that is a massive thing in this league. They have got to stand up and be counted.
“It wasn’t very nice to watch today and the supporters are quite right in their comments – I’m with them. I’m a supporter and I’d be disgusted watching that.
“I still think that we are two points from being certain of being in this league next year. We will see the character of the boys this week and hopefully go down to Bristol and put things right.
“They owe the club a performance; they owe me a performance because I feel really let down by them. Especially in the circumstances where three points would have made us safe.
“It’s got to be addressed – we’ve got two games to go. I’m sure there will be a response from today’s game in next week’s performance as we’ve got to do better.”
