Why did Lu Xiansen's band get such a bad evaluation after "Summer of the Band" was broadcast?

After the broadcast of "Summer of the Band", the reasons for the bad reviews of Lu Xiansen's band are as follows:

The band's own strength and performance level are insufficient. In the program, Lu Xiansen's performance was rated as too academic, with average singing skills and relatively average skills.

The band is not sincere enough. In the program, Lu Xiansen's band didn't thank him, but said, "Then why don't you choose?" Very boring, suspected of showing off.

The quality of lyrics is low. Although Lu Xiansen's lyrics are more talented, they are not deep enough and have great limitations. People with literary flavor will think this word is beautiful, while those without literary flavor will only think it is nonsense.
