yeah that was the case even back when the show was airing, Frankie is actually older than Justin, but on the show Malcolm is younger than Reese. So Frankie always looked younger than Justin, even though he really is older.
I like Justin's current looks. He's a very cool guy I think. He's come into his own. I think what a lot of those people on those often terrible IMDB boards don't realize (or choose to ignore), is that kids in puberty go through an often awkward, gawky stage where their limbs or some features have disproportionate growth spurts, which sparks off all those comments of 'ew, turned ugly!', 'looks like a retard' and worse comments I won't even mention here. As if they could help it, and should be stuck in a (pre)teen frame forever! It all needs some time to settle down.
I don't even bother to enter into those 'debates' anymore. I always think of these boards as open to the public, also to the actors themselves, and wonder what they would make of all those offensive comments and crazy assumptions about looks, supposed behaviour, drug use, diseases, sexual orientation etc. There's very few comments about mature interests, development as actors and such.
he has his own message board linked from his site which he posts on, so he does not need to enter the IMDb mess, lol. I bet half of those peole are still asking if he is gay. Which is the case with like all the IMDb board for male actors.
