None of the information needed to make this decision is present IMO.
Do you have $4,000,000? If so, then whatever, go ahead and play it.
Do you have $2,700? If so, then no, don't play it.
I think you are overestimating the skill of the other players in it actually. I live in the US so have not been able to play the Stars Sunday Million in quite some time, but the vast majority of the field in it always sucked. It was their big advertised tourney with a large guarantee, a relatively low buy-in and a lot of satellites; it was probably the softest weekly online tournament above microstake levels (the tough tournament back in the day was probably the $162 Stars had on Tuesday or Wednesday nights (I wanna say Wednesday?), I forget which day). None of which necessarily means your skill level is there; I don't know your skill level, so how could I know. But you also have to consider how much money you have. Large entry MTTs like this are incredible high variance; you simply shouldn't spend much of your money to enter it. And you didn't say how much money you have, so I don't see how anyone can actually give decent advice. $200 of PokerStars tournament dollars is worth like $199.50 in cash if you sell it in this thread:
