Do people actually like this movie?

Yes, guilty pleasure. The only Segal movie I watched until the end. And even more than once.

As my username (and post history) may indicate....I'm a die-hard Seagal fan.
I genuinely like the guy and his movies (I'm not one of those frat-boy ironic-type fans)
But, even though I think his fight scenes (especially the climatic 'Knife-fight) were on point......I've never been too impressed with this movie, either (despite the fact that it's his most successful role)

My problem with the movie, is (by-and-large) the pacing......It takes forever to get going, and there's little suspense leading up to things, because everything is spelt out for you. Given Seagal's previous winning formula of movies, UNDER SIEGE seems like a watered down 'variation' of the standard he'd already set. It clones DIE HARD (heavily) but at least, Bruce Willis had a vulnerability, that leant to the ensuing suspense-factor. Whereas, only four movies in, Seagal had already cemented his 'omnipotent' persona.....leading to 'UNDER SIEGE's bad-guys not standing a chance from the get-go (which is why I prefer it when Seagal plays his enraged cops out for vengeance, as opposed to putting him in a 'Right-Guy-Wrong-Place' scenario....as there's rarely pretence of suspence....just straight-up bloodshed)
A good example being, Andrew Davis throws in a scene were Seagal is (mildly) injured at one point, but it seems like an after-thought (and none of it rings true) Seagal looks more upset, that the film-makers have foisted a 'weakness' upon him, he looks a little miffed for around 20 seconds, and then the entire 'injury' is quickly forgotten about.

Plus Gary Busey is totally 'wasted' (and I don't mean inebriated and/or high on narcotics, either)

UNDER SIEGE 2 (whilst more of the same) is (at least) better paced, slicker and fully aware of how ludicrous it is (almost winking at it's audience) Whereas UNDER SIEGE is largely remembered for Erica Eleniak's tits.

Either MARKED FOR DEATH or OUT FOR JUSTICE are much better showcases for Seagal's skillset and persona.

Truth be told, I prefer a shit-ton of his more recent (DTV) fare than Under Siege (gulp!.....there, I said it)

Yes, they do.

Its Seagals best movie and one of the best war movies ever overall

It contains good action.

lol yes but most action films are pretty dumb
i loved Busey in this, and Tommy Lee Jones is great as the psycho alpha

guilty pleasure for me

I didn’t expect anything from it and thought it was better than I expected. I only want watched this for the first time recently too.

I didn’t see what was so special about Erika though plastic boobs, short hair. Meh
