AD&D Spells -- Level I MU

Here is my assessment of level I MU spells. First, Nazim's poll results. There were about 108 voters on this poll. For 9/10 folks to think something rocks, it needs to have more than 97 votes. For fewer than 1/10 to think its ever useful, then it needs to have 11 votes or less. To be in the top 20%, it needs 86+ votes. I've highlighted those extremes in blue and red respectively for you below.

My first problem is that there are too many spells. There's a lot of crap there I think and its hard to remember.

In any event, I think the top three picks are good candidates for over poweredness. Magic Missile is a staple for mid and higher level characters, who often fill their slots with nothing but magic missile to be gatling guns. Sleep is a nuke. Charm Person is often spammed. I'd slap a material component on them.

There are a lot of underpowered spells. I would move read magic and comprehend languages down to underpowered to pair them up with their weak reversals (or vice versa). I would move Mount up to the standard power because I find it to be very versatile and handy. I think you'd be safe making all those Underpowered spells level 0 cantrips, however.
